    (纽约彭博电)最新研究显示,大气中的微塑料正在加剧全球变暖,放大气候变化的影响。

    《自然·气候变化》(Nature Climate Change)期刊星期一(5月4日)发布的研究报告显示,这些细小的彩色塑料颗粒会在风的作用下在全球范围内飘散,并吸收阳光、滞留热量,从而推动气温上升。

    中国复旦大学和美国杜克大学的科学家进行的实验和大气模型显示,空气中的塑料污染物的吸热效应是黑碳的16.2%,而黑碳是仅次于二氧化碳的全球变暖第二大因素。

    科学家说,从全球范围来看,这种影响微乎其微,但在塑料污染严重的地区如太平洋部分海域,其影响却可能十分显著。在这些地区,塑料微粒的影响是黑碳的4.7倍。

    过去的研究认为,微塑料对全球变暖影响甚微,因为白色塑料颗粒会反射阳光。

    不过,复旦大学的科学家发现,大气中的塑料颗粒多数为有色颗粒,能够吸收并滞留热量。

    报告的共同作者、杜克大学气候科学家辛德尔说,他们的实验通过精确测量不同颜色颗粒吸收阳光的速率,取得了突破性进展。

  • 美军称加勒比海最新打击疑似运毒船造成2人死亡


    2026年5月5日 / 美国东部时间早上6:25 / 美联社 / 哥伦比亚广播公司新闻

    华盛顿——美国军方表示,当地时间周一,美军再次对一艘被指在加勒比海运送毒品的船只发动打击,造成2人死亡。

    特朗普政府在拉美水域炸毁疑似运毒船只的行动自9月初以来持续推进,迄今已造成至少188人死亡。此类打击行动也在东太平洋海域开展。

    尽管美国与伊朗处于战争状态,这一系列打击行动在近几周再度升级,表明政府阻止西半球所谓“毒品恐怖主义”的强硬举措并未松懈。美军尚未提供证据证明这些船只当时载有毒品。

    此次袭击是在美国集结数代以来该地区最大规模军事力量期间启动的,比今年1月抓捕时任委内瑞拉总统尼古拉斯·马杜罗的突袭行动早了数月。马杜罗被押往纽约面临贩毒指控,他已提出无罪抗辩。

    在周一的最新袭击中,美国南方司令部重申了此前的声明,称其在已知的走私路线上瞄准了疑似毒贩。该司令部在社交媒体上发布了一段视频,显示一艘船只在水面航行,随后一场大规模爆炸将船只吞没在火焰中。

    特朗普总统曾表示,美国与拉美贩毒集团处于“武装冲突”状态,并将这些袭击辩解为必要的升级行动,以遏制毒品流入美国以及造成美国人死亡的过量吸毒事件。但他的政府几乎没有提供证据支持其击毙“毒品恐怖分子”的说法。

    与此同时,批评人士对这些船只打击行动的整体合法性提出了质疑。

    Latest U.S. strike on alleged drug boat kills 2 in Caribbean, military says

    May 5, 2026 / 6:25 AM EDT / AP / CBS News

    Washington— The U.S. military said it launched another strike on a boat accused of ferrying drugs in the Caribbean Sea, killing two people Monday.

    The Trump administration’s campaign of blowing up alleged drug-trafficking vessels in Latin American waters has persisted since early September and killed at least 188 people in total. Other strikes have taken place in the eastern Pacific Ocean.

    Despite the Iran war, the series of strikes has ramped up again in recent weeks, showing that the administration’s aggressive measures to stop what it calls “narcoterrorism” in the Western Hemisphere are not letting up. The military has not provided evidence that any of the vessels were carrying drugs.

    The attacks began as the U.S. built up its largest military presence in the region in generations and came months ahead of the raid in January that captured then-Venezuelan President Nicolás Maduro. He was brought to New York to face drug trafficking charges and has pleaded not guilty.

    In the latest attack Monday, U.S. Southern Command repeated previous statements by saying it had targeted the alleged drug traffickers along known smuggling routes. It posted a video on social media showing a boat moving along the water before a massive explosion engulfs the vessel in flames.

    President Trump has said the U.S. is in “armed conflict” with cartels in Latin America and has justified the attacks as a necessary escalation to stem the flow of drugs into the United States and fatal overdoses claiming American lives. But his administration has offered little evidence to support its claims of killing “narcoterrorists.”

    Critics, meanwhile, have questioned the overall legality of the boat strikes.

  • 乌克兰抨击俄罗斯“极其虚伪” 宣称停火但袭击不断

    乌克兰总统泽连斯基星期二(5月5日)指责俄罗斯“极其虚伪”,一方面寻求停火以便在莫斯科举行5月9日胜利日阅兵式,另一方面却发动致命袭击。

    法新社报道,本周早些时候,莫斯科和基辅分别宣布了不同日期的非正式停火,但随后又进行夜间袭击,造成多人死亡。

    乌克兰官员称,俄罗斯无人机和导弹袭击了乌克兰中部波尔塔瓦州,造成一家能源公司的三名工人以及两名参与救援的救援人员死亡。

    乌克兰当局称,俄罗斯向哈尔科夫发射了11枚弹道导弹和164架无人机,造成一人死亡。

    泽连斯基在一份声明中回应说:“一方面要求停火以便举行宣传庆祝活动,另一方面却在庆祝活动前每天都进行导弹和无人机袭击,这极其虚伪。”

    “俄罗斯随时可以停火,这将停止战争和我们的反击。”

    莫斯科已宣布在5月9日二战纪念活动期间停火,基辅也表示将在5月6日停火。

    俄罗斯于2022年2月入侵乌克兰,战争已造成数十万人丧生,数百万人流离失所。

  • 美国教育部调查女子学院史密斯学院录取跨性别女性事件


    2026年5月5日 / 美国东部时间凌晨5:18 / 哥伦比亚广播公司/美联社

    美国教育部表示,已于周一启动针对马萨诸塞州女子院校史密斯学院的调查,原因是该校录取跨性别女性。

    教育部在一份新闻稿中称,史密斯学院一直在“录取生理男性”。

    该部门民权办公室开展的此次调查将审查该校是否违反了《第九条修正案》——1972年通过的一项禁止在教育领域基于性别进行歧视的法律。

    此举是特朗普政府限制美国跨性别群体权利的最新举措。该政府此前多次发表攻击跨性别群体的言论,此前曾声称《第九条修正案》禁止跨性别女性参加女子体育赛事,起诉了多个州,并对不遵守该规定的学校展开调查。

    史密斯学院是一所创办于1871年的私立文理学院,自2015年起开始录取跨性别女性,与其他多所顶尖女子学院做法一致。

    该校的招生政策曾在2013年引发关注和校园抗议活动,当时一名跨性别高中毕业生因财务援助表格上的性别身份与实际不符而被拒绝录取。

    该校官网目前规定,“所有自我认定为女性的申请者,包括顺性别女性、跨性别女性和非二元性别女性”均可申请入学。多年来,维权人士一直支持这一政策转变,称女子学院的创办初衷是为那些因性别而被边缘化的群体提供教育。

    根据女子学院联盟的数据,截至2023年秋季,美国女子学院的数量已从200多所锐减至仅30所。

    学院发言人未立即回复记者通过电子邮件提出的置评请求。

    根据教育部的新闻稿,《第九条修正案》有一项例外条款,允许院校只招收男性或只招收女性,但该条款仅“基于生理性别差异,而非主观性别认同”。

    新闻稿援引民权事务助理部长金伯利·里奇的话称:“如果招收生理男性,女子学院的存在就失去了全部意义。允许生理男性进入专为女性设立的空间,引发了关于隐私、公平以及是否遵守联邦法律的严重担忧。特朗普政府将继续维护法律,努力恢复合理准则。”

    针对史密斯学院的调查源于保守派法律组织“捍卫教育”于2025年6月向民权办公室提交的一份投诉。

    该组织在新闻稿中表示:“‘捍卫教育’及其成员反对美国K-12学校和高等教育机构中基于性别的歧视等行为。”

    拜登政府任期内曾出台新的《第九条修正案》条例,禁止基于性取向或性别认同的歧视,但该条例在2025年1月被一名联邦法官裁定因存在法律缺陷而无效。

    Education Department investigating all-women’s Smith College for admitting trans women

    May 5, 2026 / 5:18 AM EDT / CBS/AP

    The U.S. Department of Education says it opened an investigation Monday into Smith College, an all-women’s institution in Massachusetts, for admitting transgender women.

    In a press release, the department says Smith has been “admitting biological men.”

    The probe by the department’s Office of Civil Rights will look at whether the college violated Title IX, a 1972 law forbidding discrimination based on sex in education.

    The move is the latest by the Trump administration – whose rhetoric has frequently included attacks on trans people – to limit transgender rights in the U.S. The administration has said that Title IX prevents trans women from participating in women’s sports, suing several states and launching investigations into schools for not complying.

    Smith College, a private liberal arts school founded in 1871, has admitted trans women since 2015, along with many other elite women’s colleges.

    The school’s admission policies drew attention and sparked on-campus activism in 2013, when a trans high school senior was denied acceptance because her gender identity did not match the one on her financial aid forms.

    Its website now says that “any applicants who self-identify as women; cis, trans, and nonbinary women” are eligible to apply to the school. Advocates have supported the shift over the years, saying that women’s colleges were founded to educate those marginalized because of their gender.

    The number of women’s colleges in the U.S. has declined from more than 200 to just 30 as of fall of 2023, according to the Women’s College Coalition.

    A college spokesperson did not immediately respond to an emailed request for comment.

    According to the department’s news release, Title IX contains an exception that allows colleges to be all-male or all-female, but it only applies “on the basis of biological sex difference, not subjective gender identity.”

    The release quotes Assistant Secretary for Civil Rights Kimberly Richey as saying, “An all-women’s college loses all meaning if it is admitting biological males. Allowing biological males into spaces designed for women raises serious concerns about privacy, fairness, and compliance under federal law. The Trump Administration will continue to uphold the law and fight to restore common sense.”

    The investigation into Smith College stems from a complaint filed with the Office of Civil Rights in June 2025 by the conservative legal group Defending Education.

    “DE and its members oppose, among other things, discrimination on the basis of sex in America’s K-12 schools and institutions of higher education,” the organization said in a news release.

    During the Biden administration, new Title IX regulations were issued to prevent discrimination based on sexual orientation or gender identity. However, those were struck down by a federal judge in January 2025 who decided the rules had legal shortcomings.

    (曼谷综合电)中东冲突影响尚未缓解,亚洲又面临厄尔尼诺可能来袭的威胁。这可能推高能源需求、削弱水力发电和破坏农作物。

    联合国气象机构上周说,厄尔尼诺可能在今年5月至7月间形成。世界气象组织也警告,初步迹象显示强度可能较高,部分观察称之为“超级厄尔尼诺”。

    这对亚洲并非好消息,这往往意味着高温、干旱或局部暴雨等极端天气。印尼等地可能出现降雨减少,增加旱灾与林火风险。

    同时,能源经济与金融分析研究所专家哈尼娅警告,气温升高将进一步加剧能源电网压力,因为在燃料短缺背景下,人们将增加空调用电以降温。

    她说,对依赖霍尔木兹海峡石油和天然气运输的国家而言,供应紧张将导致燃料配给、需求管理以及经济活动下降,从而影响整体经济增长。

    美国为重新开放霍尔木兹海峡展开的行动正遭遇火力打击,美军在开始引导船只通过这条全球最关键航道之一时,拦截了伊朗的导弹和无人机,并摧毁了 targeting 商业船只的攻击艇。

    美国中央司令部(CENTCOM)表示,两艘悬挂美国国旗的商船已在这次被称为“自由计划”的行动中顺利通过海峡,尽管伊朗官员否认这一说法,称其“毫无根据”,并警告任何外国军事存在都将遭到攻击。

    唐纳德·特朗普总统警告称,任何伊朗袭击美国船只的行为都将遭到压倒性武力反击,称伊朗会被“从地球上彻底消灭”,而伊朗一名高级指挥官则表示,若美军“靠近并进入”海峡,美军将成为打击目标。

    本次行动迅速演变为对海峡控制权的直接考验,美军在火力下引导船只通行,同时伊朗威胁袭击任何外国军事存在——这场冲突可能将双方拖入全面对抗。

    特朗普的末日式伊朗警告推高美国全面打击威胁的风险

    特朗普在Truth Social平台发帖称,伊朗在行动期间向“无关国家”开火,包括一艘韩国货船,并暗示盟友可以加入此次行动。

    “或许现在是韩国加入任务的时候了!”他写道。

    中央司令部司令布拉德·库珀海军上将对记者表示,行动开始时,伊朗军队向受美国保护的船只发射了巡航导弹、无人机和小型快艇,目标主要是商业船只以及部分美国海军舰艇。

    库珀称,美军拦截了这些袭击并摧毁了六艘伊朗小型快艇,补充说美军“挫败了所有这些威胁”。

    他表示,两艘悬挂美国国旗的船只“顺利”通过海峡,预计将有更多船只开始利用这条航道通行。

    本次行动集结了大规模美军兵力,包括导弹驱逐舰、100余架战机、无人系统以及约15000名官兵。

    库珀表示,美国并非单独为船只护航,而是在海峡范围内提供分层“防御保护伞”,整合海军、空军和电子战能力。

    他还称,美军花了数周时间利用先进技术清理并验证了一条通行航道,首先通过派遣悬挂美国国旗的船只通过完成了测试。

    霍尔木兹海峡承担着全球约四分之一的海上石油贸易,任何中断都将对全球市场造成重大影响。

    伊朗强烈反对美国的行动,伊朗军方联合指挥部负责人阿里·阿卜杜拉希警告称,任何进入海峡的外国部队“都将遭到攻击”。

    伊朗伊斯兰革命卫队也否认有任何商船顺利通过该航道,称美国的说法“毫无根据”。

    目前的局势使得海峡陷入实际争夺之中,美国宣称已开辟一条安全的通行航线,而伊朗否认有船只通行,并威胁将发动进一步袭击。

    特朗普将“自由计划”定位为帮助“中立和无辜旁观者”的人道主义行动,称许多船只补给不足,需要协助恢复正常运营。

    但他也警告称,任何干扰行为都将遭到压倒性武力反击。

    此次行动展开之际,脆弱的停火协议出现破裂迹象,阿拉伯联合酋长国表示其防空系统拦截了从伊朗发射的弹道导弹、巡航导弹和无人机。

    尽管美国已经证明可以在重兵保护下引导船只通过海峡,但目前仍不清楚该行动能否扩大至正常商业航运规模,也不确定如果伊朗袭击加剧,能否维持安全通行。

    退休海军陆战队上校雷·格伯表示,目前鲜有独立证据表明商业航运已大规模恢复,他指出,船舶追踪数据和行业信号尚未明确反映出航运量增加。

    “我们并未看到太多相关证据,”格伯说,“大多数行业人士都表示他们仍在等待。”

    他还质疑美国是否完全化解了该航道最重大的威胁之一:海军水雷。

    “如果他们清理出了一条航道,我的第一个问题会是,‘那么你们扫过雷了吗?’”他说。

    格伯补充道,即使最初的通行行动取得成功,随着伊朗对其认为的影响力丧失做出反应,长期维持该行动可能会变得更加危险。

    “霍尔木兹海峡是伊朗的主要筹码。任何改变现状的行为都有可能回到更激烈的冲突中,”他说。

    行动的下一阶段——是否有更多船只跟进,以及袭击是否会升级——将大概率决定海峡是能够完全重新开放,还是仍将处于实际争夺状态。

    Trump opens Hormuz under fire with ‘Project Freedom’ as Iran warns of attacks

    2026-05-05 05:00 EDT / Fox News

    The operation involves guided-missile destroyers, more than 100 aircraft and roughly 15,000 service members

    Expert warns US shipping plan faces risks in Hormuz

    Retired Marine colonel says key threats remain as Iran continues attacks in the Strait.

    The U.S. operation to reopen the Strait of Hormuz is unfolding under fire, with American forces intercepting Iranian missiles and drones and destroying attack boats targeting commercial shipping as they begin moving vessels through one of the world’s most critical waterways.

    U.S. Central Command (CENTCOM) said two U.S.-flagged merchant vessels have successfully transited the strait under the effort, dubbed “Project Freedom,” even as Iranian officials rejected the claim as “baseless” and warned that any foreign military presence would be attacked.

    President Donald Trump warned that any Iranian strike on U.S. vessels would be met with overwhelming force, saying Iran would be “blown off the face of the earth,” while a senior Iranian commander said American forces would be targeted if they “approach and enter” the strait.

    The operation has quickly turned into a direct test of control over the strait, with U.S. forces moving ships under fire while Iran threatens to strike any foreign presence — a clash that could pull the two sides deeper into open conflict.

    TRUMP’S APOCALYPTIC IRAN WARNING RAISES STAKES FOR SWEEPING US STRIKE THREAT

    In a post on Truth Social, Trump said Iran had taken “shots at unrelated Nations” during the operation, including a South Korean cargo ship, and suggested allies could join the effort.

    “Perhaps it’s time for South Korea to come and join the mission!” he wrote.

    CENTCOM Commander Adm. Brad Cooper told reporters that Iranian forces launched cruise missiles, drones and small boats at vessels under U.S. protection as the operation began, targeting primarily commercial shipping as well as some U.S. Navy ships.

    U.S. forces responded by intercepting the attacks and destroying six Iranian small boats, Cooper said, adding that American forces “defeated each and every one of those threats.”

    He said the two U.S.-flagged ships transited the strait “uneventfully” and that additional vessels are expected to begin moving to take advantage of the passage.

    The operation involves a large U.S. military presence, including guided-missile destroyers, more than 100 aircraft, unmanned systems and roughly 15,000 service members.

    Cooper said the U.S. is not escorting ships individually but instead providing a layered “defensive umbrella” across the strait, combining naval, air and electronic warfare capabilities.

    U.S. forces also spent weeks using advanced technology to clear and validate a transit pathway, which was tested by sending U.S.-flagged ships through first, he said.

    The Strait of Hormuz carries roughly a quarter of the world’s seaborne oil trade, making any disruption a major concern for global markets.

    Iran has sharply rejected the U.S. operation, with Ali Abdollahi, head of the Iranian military’s unified command, warning that any foreign forces entering the strait “will be attacked.”

    Iran’s Revolutionary Guard Corps also has denied that any commercial ships successfully transited the waterway, calling U.S. claims “baseless.”

    The developments leave the strait effectively contested, with the U.S. asserting it has opened a secure transit route while Iran denies that ships are moving and threatens further attacks.

    Admiral Charles Bradford “Brad” Cooper II, Commander of U.S. Central Command, speaks during a joint press conference with U.S. Secretary of War Pete Hegseth, at CENTCOM headquarters at MacDill Air Force Base in Tampa, Florida, on March 5, 2026.(Octavio JONES / AFP via Getty Images)

    Trump has framed “Project Freedom” as a humanitarian effort to help “neutral and innocent bystanders,” saying many ships are running low on supplies and need assistance to resume normal operations.

    But he has also warned that any interference would be met with overwhelming force.

    The operation is unfolding as the fragile ceasefire shows signs of fraying, with the United Arab Emirates saying its air defenses engaged ballistic missiles, cruise missiles and drones launched from Iran.

    While the U.S. has demonstrated it can move ships through the strait under heavy military protection, it remains unclear whether the effort can scale to normal commercial traffic levels or sustain safe passage if Iranian attacks intensify.

    Retired Marine Corps Col. Ray Gerber said there is limited independent evidence so far that commercial shipping has resumed at scale, noting that maritime tracking data and industry signals have yet to clearly reflect increased traffic.

    “We’re not really seeing a lot of evidence of it,” Gerber said. “Most of the industry is saying they’re still waiting.”

    He also questioned whether the U.S. has fully mitigated one of the most significant threats in the waterway: naval mines.

    “If they’ve cleared a corridor, my first question is going to be, ‘So you’ve swept it for mines?’” he said.

    Gerber added that even if initial transits succeed, sustaining the operation could become more dangerous over time as Iran responds to what it sees as a loss of leverage.

    “The Strait of Hormuz is Iran’s primary leverage point. Any changes to that status quo raise the possibility of returning to more active conflict,” he said.

    The next phase of the operation — whether more ships follow and whether attacks escalate — will likely determine whether the strait can be fully reopened or remains effectively contested.

    厄尔尼诺现象或来袭 亚洲面临能源粮食双重压力

    (曼谷综合电)中东冲突影响尚未缓解,亚洲又面临厄尔尼诺可能来袭的威胁。这可能推高能源需求、削弱水力发电和破坏农作物。

    联合国气象机构上周说,厄尔尼诺可能在今年5月至7月间形成。世界气象组织也警告,初步迹象显示强度可能较高,部分观察称之为“超级厄尔尼诺”。

    这对亚洲并非好消息,这往往意味着高温、干旱或局部暴雨等极端天气。印尼等地可能出现降雨减少,增加旱灾与林火风险。

    同时,能源经济与金融分析研究所专家哈尼娅警告,气温升高将进一步加剧能源电网压力,因为在燃料短缺背景下,人们将增加空调用电以降温。

    她说,对依赖霍尔木兹海峡石油和天然气运输的国家而言,供应紧张将导致燃料配给、需求管理以及经济活动下降,从而影响整体经济增长。

    能源智库Ember亚洲高级分析师迪尼塔指出,湄公河流域国家、尼泊尔及马来西亚部分地区尤为脆弱。

    农业方面,研究机构BMI警告,如果农产品价格上涨不足以抵消成本增加,农民利润将被压缩,可能减少化肥使用。这会导致产量下降,从而加剧食品价格上涨和粮食安全问题。

    专家认为,气候变化正加剧极端天气,各国需提升能源与供应体系韧性,加快发展可再生能源与分散式电网,以应对未来不确定性。

    一系列五月初选将考验唐纳德·特朗普对共和党的掌控力度,以及这位总统在共和党选民挑选候选人时将扮演的角色——如今他再也不会出现在选票上了。

    周二的印第安纳州初选中,特朗普介入了七场通常关注度不高的州参议院席位角逐,旨在清除那些拒绝他重新划分联邦国会选区地图要求的共和党保守派老派人士。

    这是本月特朗普可能发挥主导作用的多场初选的首场。后续还有肯塔基州联邦国会众议院席位角逐,特朗普正试图推翻他最主要的保守派挑战者之一——众议员托马斯·马西;以及得克萨斯州参议院决选,尽管共和党领袖希望特朗普支持参议员约翰·康恩而非总检察长肯·帕克斯顿,但特朗普并未介入这场选举,同样备受关注。

    俄亥俄州也将于周二举行初选。以下是印第安纳州和俄亥俄州初选的看点:

    特朗普的复仇行动

    去年12月,印第安纳州参议院共和党超级多数党团无视特朗普数月的游说,否决了一份新的国会选区地图——该地图本可能帮助共和党在11月的中期选举中拿下该州目前由民主党占据的两个联邦众议院席位,这让总统颜面尽失。

    迈克尔·康罗伊/美联社

    如今,特朗普正寻求报复——他为八位投票反对重新划分选区地图、今年面临连任的共和党州参议员中的七位背书了初选挑战者。

    这些通常关注度极低的选举结果,将对共和党产生远超寻常的影响:该党很快将不得不面对后特朗普时代的政治格局。这些选举将考验选民是否愿意无视特朗普的意愿,给予民选官员另起炉灶的空间。

    印第安纳州参议院临时议长罗德里克·布雷因重新划分选区一事惹怒了特朗普,但他本人并未在周二的选举中参选。他告诉美国有线电视新闻网的达纳·巴什,这类初选通常是围绕“本土议题”展开的。

    “但这次不一样,”布雷说道,“这场角逐真正的驱动力来自印第安纳州以外,主要是华盛顿特区,资金也同样来自印第安纳州之外。”

    以下是需要关注的印第安纳州州参议院共和党初选席位:

    • 第1选区:参议员丹·德努尔克面临特朗普背书的特雷弗·德弗里斯的挑战。
    • 第11选区:参议员琳达·罗杰斯面临特朗普背书的布莱恩·施穆茨勒的挑战。
    • 第19选区:参议员特拉维斯·霍德曼面临特朗普背书的布拉夫顿市议会成员布雷克·菲希特的挑战。
    • 第21选区:参议员吉姆·巴克面临特朗普背书的蒂普顿县委员特蕾西·鲍威尔的挑战。
    • 第23选区:参议员斯宾塞·迪里面临特朗普背书的宝拉·科彭哈弗的挑战,后者是支持特朗普的副州长米迦·贝克威斯的助手。
    • 第38选区:参议员格雷格·古德面临特朗普背书的维戈县议会成员布伦达·威尔逊的挑战。
    • 第41选区:参议员格雷格·沃克面临特朗普背书的州众议员米歇尔·戴维斯的挑战。

    转折点组织的考验

    就在查理·柯克遇刺的23天前,这位保守派活动人士响应特朗普的呼吁,在印第安纳州推动重新划分选区——他警告那些犹豫不决的州议员,他联合创立的组织“转折点美国”将致力于驱逐投票反对新地图的在任议员。

    “是时候让共和党人强硬起来了,”他在X平台上写道。

    近几个月来,“转折点美国”及其政治宣传分支“转折点行动”一直在践行柯克的初选承诺。

    转折点组织组织了多场集会——部分活动与活动人士斯科特·普雷斯勒一同举办,并在社交媒体上吹嘘自己正将组织者空运至该州。

    这是特朗普政治盟友更广泛行动的一部分。与班克斯结盟的团体已投入数百万美元投放针对在任议员的电视广告。“增长俱乐部”在针对潜在选民的直邮宣传中处于领先地位。而转折点组织则负责地面行动,争取动员支持特朗普的选民投票。

    此次选举结果将成为早期风向标,检验在特朗普2024年竞选地面行动中发挥重要作用的转折点组织,是否仍有足够影响力在未来塑造共和党选举结果。该组织今年面临的挑战更大:2024年的成功得益于动员年轻选民投票,但在非总统选举年,这一群体的投票率通常更低。

    激战的托莱多

    去年秋天,俄亥俄州重新划分选区委员会在今年中期选举前批准了新的联邦众议院选区地图,位于托莱多的第9选区——此前已是民主党众议员马西·卡普图尔占据的竞争激烈选区——变得对共和党更加有利。

    多名共和党人正争夺挑战卡普图尔的资格。参选者包括2024年以不到一个百分点的差距输给卡普图尔的前州众议员德里克·梅林,以及州众议员乔希·威廉姆斯和前移民和海关执法局副局长麦迪逊·谢汉。

    此次选举结果将为今年秋季共和党在整体不利的全国国会环境下最有望拿下的席位之一铺平道路。

    俄亥俄州参议院、州长竞选格局基本确定

    将在11月登上俄亥俄州选票顶端并吸引全国高度关注的两场初选几乎没有悬念。

    在竞选第四个任期失败两年后,民主党前联邦参议员谢罗德·布朗将尝试政治复出,挑战共和党参议员乔恩·赫斯特德。布朗面临一位名不见经传的民主党对手,而赫斯特德在共和党初选中无对手。

    正在直播 CNN:特朗普的“让美国再次伟大”联盟在俄亥俄出现裂痕了吗?

    尽管还有其他候选人参选,但接替即将卸任的共和党州长迈克·德怀恩的竞选也几乎板上钉钉:民主党人、俄亥俄州前卫生部门主任艾米·阿克顿预计将对阵共和党人、企业家兼2024年总统竞选参与者维韦克·拉马斯瓦米。

    印第安纳州共和党众议员面临挑战

    众议员吉姆·贝尔德的妻子因车祸受伤去世两个月后,这位共和党人在初选中面临州众议员克雷格·哈格德的严峻挑战。

    现年80岁的贝尔德于2018年首次当选该席位,今年1月获得了特朗普的背书。而哈格德则得到印第安纳州总检察长托德·罗基塔的支持,罗基塔在贝尔德之前曾担任第4选区议员。

    这并非一场典型的温和派对阵保守派的初选对决。贝尔德一直与总统保持紧密结盟,而罗基塔称哈格德是“强硬的保守派斗士”。

    What to watch in Tuesday’s primaries in Indiana and Ohio

    A set of May primaries will test the strength of Donald Trump’s grip on the Republican Party and the role the president intends to play as GOP voters pick their candidates knowing he’ll never again appear on the ballot.

    In Indiana on Tuesday, Trump is intervening in seven ordinarily sleepy state Senate races, seeking to purge a GOP old guard that rejected his demands to redistrict the state’s US House map.

    It’s the first of several primaries in which Trump could play a dominant role this month — with a US House race in Kentucky, where Trump is seeking to oust one of his foremost conservative challengers, Rep. Thomas Massie, and a Senate runoff in Texas, where Trump has stayed out of the race despite GOP leaders’ hopes he would back Sen. John Cornyn over Attorney General Ken Paxton, also being closely watched.

    Ohio will also hold its primary on Tuesday. Here’s what to watch in Indiana and Ohio:

    Trump’s revenge campaign

    Indiana’s Senate Republican supermajority embarrassed the president in December, when it ignored his months of lobbying and voted down a new congressional map that would have likely allowed the party to win the state’s two Democratic-held US House seats in November’s midterms.

    Indiana Lt. Gov. Micah Beckwith announces the results of a vote to redistrict the state’s congressional map in December 2025 at the Statehouse in Indianapolis.

    Now, Trump is looking for payback — endorsing primary challengers to seven of the eight Republican state senators who voted against redistricting and who are up for reelection this year.

    The outcome of those typically low-profile races will have outsize ramifications for a GOP that will soon be forced to grapple with what the post-Trump political landscape will look like. These races will test whether voters are willing to ignore Trump’s wishes and give their elected officials room to go in another direction.

    Indiana Senate President Pro Tem Rodric Bray — who has drawn Trump’s ire over redistricting but is not on the ballot himself Tuesday — told CNN’s Dana Bash that such primary contests are usually fought over “home-grown issues.”

    “That’s not what this is,” Bray said. “This is really driven from outside the state of Indiana, mostly in Washington, DC, and the money’s coming from outside Indiana as well.”

    These are the Indiana state Senate Republican primary races to watch:

    • District 1: Sen. Dan Dernulc faces Trump-backed Trevor De Vries.
    • District 11: Sen. Linda Rogers faces Trump-endorsed Brian Schmutzler.
    • District 19: Sen. Travis Holdman faces Trump-endorsed Bluffton City Councilman Blake Fiechter.
    • District 21: Sen. Jim Buck faces Trump-backed Tracey Powell, a Tipton County commissioner.
    • District 23: Sen. Spencer Deery faces Trump-backed Paula Copenhaver, an aide to the Trump-aligned Lt. Gov. Micah Beckwith.
    • District 38: Sen. Greg Goode faces Vigo County Councilwoman Brenda Wilson, whom Trump endorsed.
    • District 41: Sen. Greg Walker faces Trump-endorsed state Rep. Michelle Davis.

    Turning Point’s test

    Twenty-three days before Charlie Kirk was killed, the conservative activist took up Trump’s push for redistricting in Indiana — warning state lawmakers who were balking that Turning Point USA, the organization he co-founded, would work to oust incumbents who voted against the new map.

    “It’s time for Republicans to be TOUGH,” he wrote on X.

    In recent months, Turning Point USA and its political advocacy arm, Turning Point Action, have sought to see Kirk’s primary pledge through.

    Turning Point has organized a series of rallies — some alongside activist Scott Presler — and boasted on social media that it was flying organizers into the state.

    It’s part of a broader effort by Trump’s political allies. Groups aligned with Banks have poured millions into television advertisements targeting the incumbents. The Club for Growth has led the way in direct mail to potential voters. And Turning Point is running the ground game, seeking to turn out voters loyal to Trump.

    The outcome will be an early gauge of whether Turning Point, which played an important role in Trump’s 2024 ground game, can remain enough of a force to shape outcomes in the Republican Party moving forward. The group’s challenge this year is heightened by the fact that its success in 2024 came from pushing young voters to the polls, but that demographic is often harder to turnout in non-presidential contests.

    Battleground Toledo

    After an Ohio redistricting commission green-lit a new US House map last fall ahead of this year’s midterms, the Toledo-based 9th District — already competitive territory represented by Democratic Rep. Marcy Kaptur — become even more favorable to the GOP.

    Several Republicans are vying to take on Kaptur. The field includes former state Rep. Derek Merrin, who lost to Kaptur by less than a percentage point in 2024, as well as state Rep. Josh Williams and former Immigration and Customs Enforcement Deputy Director Madison Sheahan.

    Ohio’s 9th Congressional District is being fought for by incumbent U.S. Rep. Marcy Kaptur, D-Toledo, and state Rep. Derek Merrin, R-Monclova. Merrin recently held a campaign event for 80 at the Sandusky County Republican Party campaign headquarters.

    The outcome will set the stage for what’s expected to be one of the GOP’s best pickup opportunities on a difficult national congressional environment this fall.

    Field set for Ohio Senate, governor races

    There’s little drama in the primaries for the two races that will top Ohio’s ballots, and draw intense national attention, in November.

    Two years after losing his bid for a fourth term, Democratic former US Sen. Sherrod Brown will attempt a political comeback, challenging Republican Sen. Jon Husted. Brown faces a little-known Democratic opponent, and Husted is unopposed in the Republican primary.

    streaming now CNN Is Donald Trump’s MAGA coalition cracking in Ohio?

    Though others are on the ballot, the race to replace outgoing Republican Gov. Mike DeWine is also all but official: Democrat Amy Acton, the former director of the Ohio Department of Health, is expected to face Republican Vivek Ramaswamy, the entrepreneur and 2024 presidential contender.

    Indiana Republican congressman faces challenge

    Two months after Rep. Jim Baird’s wife died of injuries she sustained in a car crash, the Republican faces a serious primary challenger in state Rep. Craig Haggard.

    Baird, 80, first won the seat in 2018. He was endorsed by Trump in January. Haggard, meanwhile, is backed by Indiana Attorney General Todd Rokita, who held the 4th District seat before Baird.

    This isn’t a standard moderate-vs.-conservative primary battle. Baird has closely aligned himself with the president, and Rokita called Haggard a “strong conservative fighter.”
