哥伦比亚广播公司新闻的《战场追踪》民调今年回归2026年中期选举，捕捉选民关注的议题、全美各地值得关注的关键群体，以及这些因素对各选区、席位预估和美国众议院控制权的影响。
每个选区和州都至关重要，但哥伦比亚广播公司新闻同时锁定了9场关键参议院竞选和42场众议院竞选，这些选举或将决定国会多数席位归属——所有结果都可能随着竞选推进而发生变化。
民主党和共和党正聚焦参众两院的少量竞选席位，力争在今年秋季的中期选举中拿下国会控制权。
目前在参众两院都占据多数席位的共和党处境脆弱，主要原因在于不受欢迎的伊朗战争以及持续高企的生活成本经济压力。
参议院
共和党目前拥有53个参议院席位，民主党拥有47个。共和党需要捍卫的22个席位中，多数都位于特朗普2024年轻松获胜的州。民主党需要净增4个席位才能拿下多数席位，同时还要捍卫部分席位以应对共和党挑战。
以下是2026年9场值得关注的参议院竞选：
阿拉斯加州
共和党现任参议员丹·沙利文与前民主党众议员玛丽·佩尔托拉是阿拉斯加州四党初选的领跑者，另有一位与现任议员同名的候选人也将参选。阿拉斯加自2008年以来从未选出过民主党参议员，但民主党将这场竞选视为夺取席位的机会。
艾奥瓦州
随着参议员乔尼·恩斯特宣布不寻求连任，共和党众议员阿什利·辛森与州众议员乔希·图雷克将在艾奥瓦州展开角逐。近年来该州整体转向右翼，但由于生活成本问题和特朗普的关税政策影响了艾奥瓦选民，这场竞选的激烈程度超出预期。
缅因州
共和党现任参议员苏珊·柯林斯将迎战特洛伊·杰克逊。格雷厄姆·普拉特纳今年7月因性侵犯指控退出竞选后，杰克逊成为民主党提名候选人。柯林斯此前的连任竞选均成功化险为夷，但民主党对拿下该席位持乐观态度，因为2024年卡玛拉·哈里斯在缅因州的领先优势接近7个百分点。
密歇根州
参议员加里·彼得斯宣布退休后，前共和党众议员迈克·罗杰斯与民主党人阿卜杜勒·埃尔赛义德将争夺密歇根州的开放席位。埃尔赛义德是进步派人士，曾担任密歇根州卫生官员，在有分歧的民主党初选中击败了更温和的对手；而罗杰斯曾在去年的参议院选举中挑战埃莉萨·斯洛特金失利，此次再次参选。
俄亥俄州
共和党现任参议员乔恩·赫斯特德将迎战前参议员谢罗德·布朗的回归竞选。布朗去年在俄亥俄州另一个参议院席位的连任竞选中落败。民主党希望凭借布朗的工人阶级形象助其击败前副州长赫斯特德——赫斯特德去年在万斯当选副总统后被任命填补其空缺席位。
得克萨斯州
得克萨斯州总检察长肯·帕克斯顿与州众议员詹姆斯·塔莱里科将在这个“孤星之州”展开备受关注的角逐。帕克斯顿击败了现任共和党参议员约翰·科宁后，民主党夺取该席位的机会有所提升，原因在于帕克斯顿过往的个人争议以及更为保守的立场。但共和党仍对保住该席位充满信心，不过部分共和党人承认这场竞选将十分艰难且耗资巨大。
佐治亚州
共和党众议员迈克·科林斯将在佐治亚州挑战民主党现任参议员乔恩·奥索夫，这场竞争曾被视为共和党最容易拿下的席位之一。但混乱的共和党初选推迟了共和党击败这位首位任期参议员的大选攻势。
北卡罗来纳州
随着共和党参议员汤姆·蒂利斯宣布不寻求连任，前民主党州长罗伊·库珀与前共和党全国委员会主席迈克尔·沃特利将争夺北卡罗来纳州的参议院席位。民主党将该州视为关键目标，认为这是本届选举周期中夺取席位的最佳机会。
新罕布什尔州
参议员珍妮·沙欣退休后，民主党众议员克里斯·帕帕斯与前共和党参议员约翰·苏努努将角逐新罕布什尔州的开放参议院席位。新罕布什尔州自2010年以来从未选出过共和党参议员，但共和党对苏努努的参选前景抱有希望——苏努努家族在该州政坛一直占据主导地位。
众议院
全部435个众议院席位都将参与本次选举，拿下218个席位即可获得多数控制权。目前众议院席位差距极小：共和党拥有218个席位，另有一位独立议员与共和党团结合党，民主党拥有214个席位，另有两个席位空缺。
以下是42场值得关注的众议院竞选：
亚利桑那州第1国会选区
共和党人杰·费利与民主党人阿米什·沙阿将争夺接替八届共和党众议员大卫·施魏克特的席位，施魏克特此前竞选州长失利。费利曾是NFL球员、哥伦比亚广播公司体育频道前分析师，最初在另一个选区参选，后应特朗普总统的要求更换了选区。沙阿2024年曾挑战施魏克特未果。
亚利桑那州第6国会选区
共和党现任众议员胡安·西斯科马尼将迎战海军陆战队老兵乔安娜·门多萨，该选区涵盖图森郊区以及该州东南部沿美墨边境的区域。
加利福尼亚州第13国会选区
民主党现任众议员亚当·格雷的席位是众议院共和党竞选团队的首要目标之一。格雷2024年以不到200票的微弱优势 flipping该席位，2022年他曾以不到600票的差距落败。在6月的无党派初选中，他相对于共和党候选人、海军陆战队老兵凯文·林肯拥有显著优势。
加利福尼亚州第12国会选区
共和党现任众议员大卫·瓦拉达奥是2021年因国会山骚乱投票弹劾特朗普总统的仅剩两名众议院共和党议员之一。华盛顿州众议员丹·纽豪斯已退休，瓦拉达奥是其中唯一寻求连任的人。在重新划分后的选区内，他将对阵民主党人兰迪·维列加斯。
加利福尼亚州第45国会选区
民主党现任众议员德里克·特兰的选区因州长加文·纽森的重新划分计划进行了调整，新选区仅以4个百分点的优势支持哈里斯。众议院共和党竞选团队正支持前塞里托斯市长张钟元，目标拿下这个位于奥兰治县附近的选区。
加利福尼亚州第48国会选区
共和党人吉姆·德斯蒙德与民主党人马尼·冯·维尔珀特将参选接替即将离任的共和党众议员达雷尔·伊萨，该选区是重新划分后的南加州选区。
科罗拉多州第8国会选区
2025年 flipping民主党席位的共和党现任众议员加布·埃文斯将寻求连任，对手是民主党进步派州众议员曼尼·鲁蒂内尔。该选区位于丹佛以北，拥有庞大的拉丁裔人口。
佛罗里达州第14国会选区
民主党现任众议员凯西·卡斯托所在的坦帕地区选区经过重新划分后对共和党更为友好，但目前仍被评为“倾向民主党”。前州众议员迈克·贝尔特兰在竞争激烈的共和党初选中胜出，将在秋季对阵卡斯托。
佛罗里达州第22国会选区
该选区被操纵划分得更有利于共和党后，现任民主党众议员洛伊丝·弗兰克尔转而选择参选第23选区。民主党人皮亚·丹迪亚在8月初选胜出，共和党人凯西·阿斯卡尔在竞争激烈的共和党初选中获胜。两党的竞选团队都将目光投向这个位于棕榈滩县的选区。
佛罗里达州第25国会选区
民主党现任众议员贾里德·莫斯科维茨将在这里寻求连任，尽管博卡拉顿地区的选区边界调整后对共和党更为有利。莫斯科维茨的对手是前博卡拉顿市长斯科特·辛格。
艾奥瓦州第1国会选区
民主党人克里斯蒂娜·博安南将第三次尝试击败共和党现任众议员玛丽安娜特·米勒-米克斯。自2020年以来，米勒-米克斯多次在势均力敌的选举中获胜。
艾奥瓦州第2国会选区
共和党人乔·米切尔与民主党人林赛·詹姆斯将参选接替竞选参议员的共和党众议员阿什利·辛森。
艾奥瓦州第3国会选区
共和党现任众议员扎克·纳恩将捍卫自己的席位，对手是民主党人萨拉·特龙·加里奥特。纳恩自2023年以来代表这个位于得梅因地区的选区，2024年他以不到4个百分点的优势成功连任。
密歇根州第4国会选区
资深共和党众议员比尔·惠曾加将迎战民主党州参议员肖恩·麦卡恩的挑战。
密歇根州第7国会选区
2024年首次当选的共和党众议员汤姆·巴雷特是少数支持民主党主导的战争权力决议、限制特朗普总统对伊朗行动的共和党人之一。他的对手是民主党人威廉·劳伦斯——“日出运动”联合创始人，曾是美国民主社会主义者成员。
密歇根州第8国会选区
托马斯·史密斯暂停竞选后击败了特朗普支持的候选人，赢得共和党初选，将对阵民主党现任众议员克里斯汀·麦克唐纳·里维特。尽管该选区2024年选出了麦克唐纳·里维特，但同时也投票支持了特朗普总统。
密歇根州第10国会选区
共和党人迈克尔·布沙尔与民主党人克里斯蒂娜·海因斯将争夺开放席位，该席位目前由竞选密歇根州州长的共和党众议员约翰·詹姆斯担任。
内布拉斯加州第2国会选区
共和党人布林克·哈丁与民主党人丹尼斯·鲍威尔将有望接替即将退休的共和党众议员唐·培根，该选区位于奥马哈地区。过去三十年来，该席位除了两年外一直由共和党掌控，但在过去五届总统选举中，该选区有三次投票支持了民主党候选人。
内华达州第3国会选区
电子游戏音乐作曲家马蒂·奥唐奈希望挑战位于拉斯维加斯部分区域的第3选区民主党现任众议员苏西·李。
新罕布什尔州第1国会选区
民主党众议员克里斯·帕帕斯今年选择参选参议员，导致这个摇摆席位出现空缺。帕帕斯自2017年以来一直担任该席位议员，此前该席位曾五次在两党之间交替。即将退休的参议员珍妮·沙欣的女儿、民主党人斯特凡妮·沙欣将对阵共和党人安东尼·迪洛伦佐。
新泽西州第7国会选区
共和党现任众议员汤姆·基恩 Jr.将迎战民主党人丽贝卡·贝内特，此前他今年早些时候曾长期缺席国会。6月重返工作岗位后，他透露自己被诊断出抑郁症并住院接受治疗。
新墨西哥州第2国会选区
海军陆战队老兵格雷格·坎宁安将挑战民主党现任众议员加布·瓦斯克斯，该选区覆盖该州南部半部分区域，包括阿尔伯克基的部分地区。瓦斯克斯2022年当选， flipping该席位。
纽约州第3国会选区
民主党现任众议员汤姆·苏奥齐将在长岛选区迎战前纽约州众议员迈克·勒佩特里。这个长期由民主党掌控的选区2022年 flipped共和党，但在前众议员乔治·桑托斯被国会开除后，苏奥泽在特别选举中赢得该席位。他2024年成功连任，尽管特朗普总统在该选区获胜。
纽约州第4国会选区
2024年，民主党众议员劳拉·吉伦击败了共和党现任众议员安东尼·德斯波西托——后者2022年曾在开放的长岛席位竞选中击败吉伦。她将迎战当地税务官员、共和党候选人珍妮妮·德里斯科尔。
纽约州第17国会选区
共和党现任众议员迈克·劳勒自2023年以来一直担任哈德逊河谷下游选区的议员，他将自己塑造为能够跨党派合作的温和派人士。民主党人凯特·康利是国家安全专家、陆军作战老兵，在宣布参选前不久才搬到该选区，不过她在该地区长大。2024年哈里斯在该选区以微弱优势击败特朗普。
纽约州第19国会选区
民主党现任众议员乔希·莱利将在这个竞争激烈的选区寻求连任，对手是共和党州参议员彼得·奥伯拉克。
北卡罗来纳州第1国会选区
这场竞选是共和党人劳里·巴克哈特与民主党现任众议员唐·戴维斯的重赛。该选区经州共和党人几轮操纵划分后进一步右倾，戴维斯面临艰难的连任竞选。
北卡罗来纳州第11国会选区
众议院道德委员会认定共和党现任众议员查克·爱德华兹对两名下属女性存在“持续不专业且不当行为”后，爱德华兹放弃了连任竞选。共和党州众议员詹妮弗·巴尔科姆接替爱德华兹参选，将对阵民主党人杰米·阿杰尔。
俄亥俄州第1国会选区
根据俄亥俄州新的法院批准的国会选区地图，共和党将目标瞄准这个自2023年以来由民主党众议员格雷格·兰兹曼代表的选区。空军老兵、前中央情报局特工埃里克·康罗伊在特朗普的支持下赢得竞争激烈的共和党初选。尽管按照新边界划分后特朗普赢得了该选区，但哥伦比亚广播公司新闻将该选区评为“倾向民主党”。
俄亥俄州第9国会选区
选民将再次在资深民主党众议员马西·卡普图尔与共和党人德里克·梅林之间做出选择。梅林2024年曾挑战卡普图尔，以约2400票的差距落败——这一差距刚好超过自动重新计票的阈值。俄亥俄州西北部选区2025年10月进行了重新划分，成为更有利于共和党的席位。
宾夕法尼亚州第1国会选区
民主党人鲍勃·哈维将迎战共和党现任众议员布莱恩·菲茨帕特里克——菲茨帕特里克是少数投票支持限制特朗普总统进一步打击伊朗能力的众议院共和党人之一。菲茨帕特里克2024年以近13个百分点的优势成功连任。
宾夕法尼亚州第7国会选区
共和党现任众议员瑞安·麦肯齐2024年 flipping该选区，以1个百分点的优势击败民主党现任议员。今年他将迎战退休消防员鲍勃·布鲁克斯。
宾夕法尼亚州第8国会选区
共和党现任众议员罗布·雷斯纳汉将对阵斯克兰顿市长佩奇·科涅蒂。2024年，雷斯纳汉以不到2个百分点的优势击败民主党现任众议员马特·卡特赖特。
宾夕法尼亚州第10国会选区
这场竞选是前电视新闻主播贾内尔·斯泰尔森与共和党现任众议员斯科特·佩里的重赛。2024年，斯泰尔森在覆盖哈里斯堡、约克及周边地区的选区中以约5000票的差距惜败佩里。
得克萨斯州第15国会选区
特哈诺音乐艺人鲍比·普利多将尝试在这个拉丁裔占多数的选区击败共和党现任众议员莫妮卡·德拉·克鲁兹。德拉·克鲁兹2022年 flipping该席位，2024年特朗普在该选区的领先优势接近20个百分点，但此后拉丁裔选民呈现向左倾斜的趋势。
得克萨斯州第28国会选区
得克萨斯州重新划分国会选区后，任职11届的民主党现任议员亨利·库埃拉尔的选区对共和党更为友好。长期以来共和党一直将库埃拉尔视为目标，认为该选区是优先竞选目标，但库埃拉尔一直表现出较强的韧性。他还面临联邦贿赂和洗钱指控，但特朗普总统去年12月赦免了他。库埃拉尔将在11月对阵共和党人、韦伯县法官塔诺·赫里纳。
得克萨斯州第34国会选区
2024年特朗普在得克萨斯州拉丁裔选民中取得进展，尽管他赢得了美墨边境沿线的第34选区，但民主党现任众议员文森特·冈萨雷斯在2024年的竞选中成功连任。重新划分后该选区对共和党略微更友好，成为众议院共和党竞选团队的首要目标之一。共和党人迈拉·弗洛雷斯将第三次在大选中挑战冈萨雷斯。
得克萨斯州第35国会选区
经过得克萨斯州的选区操纵，新的第35选区对共和党更为友好，仅保留了当前选区10%的区域。该选区不再包括民主党票仓奥斯汀——现任众议员格雷格·卡萨罗的居住地，这使得该选区更有利于共和党。卡萨罗选择在新的第37选区参选，导致第35席位出现空缺。民主党人约翰尼·加西亚与共和党人卡洛斯·德拉·克鲁兹（众议员莫妮卡·德拉·克鲁兹的兄弟）在竞争激烈的初选中胜出，将在投票日展开角逐。
弗吉尼亚州第1国会选区
共和党现任众议员罗布·威特曼希望将共和党对该席位的控制权再延续两年。自1977年以来，该席位一直由共和党掌控。威特曼的民主党对手是亨里科县首席检察官香农·泰勒。
弗吉尼亚州第2国会选区
共和党现任众议员詹·基冈斯将捍卫自己的席位，对手是前民主党众议员伊莱恩·卢里亚。卢里亚曾担任该选区议员两任，2022年因重新划分导致该选区更有利于共和党而输给基冈斯。
华盛顿州第3国会选区
民主党现任众议员玛丽·格卢森坎普·佩雷斯曾两次击败极右翼保守派乔·肯特，肯特之后曾担任特朗普的反恐负责人，后因抗议伊朗战争辞职。今年她将迎战自2012年当选州参议员以来担任过多个领导职务的约翰·布劳恩。2024年特朗普在该选区获胜。
威斯康星州第3国会选区
这场竞选是民主党人丽贝卡·库克与共和党现任议员德里克·范·奥尔登的重赛，范·奥尔登将寻求第三个任期。库克曾拥有一家商店，疫情期间关闭，她2024年以不到3个百分点的差距输给范·奥尔登。她的网站显示，她一边竞选一边兼职做服务员。
2026 midterm election races to watch
2026-09-13T09:18:53-0400 / https://www.cbsnews.com/news/2026-midterm-election-races/
CBS News’ Battleground Tracker polling is back for 2026, capturing what’s on voters’ minds and the key groups to watch coast to coast, as well as what it means for districts, seat estimates and control of the U.S. House of Representatives.
Every district and state matters, but CBS News also identifies nine key Senate and 42 House races that will likely decide the majority — all of which can change as the campaign rolls on.
Democrats and Republicans are focusing on a small number of races in the House and the Senate as they fight for control of Congress in the midterm elections this fall.
Republicans, who currently have the majority in both chambers, are vulnerable primarily because of the unpopular Iran war and continuing cost-of-living economic pressure.
Senate
Republicans have 53 seats, and Democrats have 47. Most of the 22 seats the GOP is defending are in states Mr. Trump easily won in 2024. Democrats must add a net total of four seats to take the majority while also defending a few seats against GOP challenges.
Here are the nine 2026 Senate races to watch:
Alaska
GOP Sen. Dan Sullivan and former Democratic Rep. Mary Peltola are the front-runners in Alaska’s top-four primary, where another candidate by the same name as the incumbent is also on the ballot. Alaska hasn’t elected a Democrat to the Senate since 2008, but the party is eyeing the race as a pickup opportunity.
Iowa
GOP Rep. Ashley Hinson and state Rep. Josh Turek are facing off in Iowa after Sen. Joni Ernst decided not to seek reelection. The race has grown surprisingly competitive in a state that’s shifted to the right in recent years, as affordability issues and the Trump tariff policies weigh on Iowans.
Maine
GOP Sen. Susan Collins is defending her seat against Troy Jackson, who became the Democratic nominee after Graham Platner bowed out of the race in July following a sexual assault allegation. Collins has survived challenges in previous reelection fights, but Democrats are optimistic about their chances in a state that Kamala Harris won in 2024 by almost 7 points.
Michigan
Former GOP Rep. Mike Rogers and Democrat Abdul El-Sayed are vying for an open seat in Michigan after Sen. Gary Peters decided to retire from Congress. El-Sayed is a progressive former Michigan health official who defeated a more moderate opponent in a divisive Democratic primary, while Rogers is seeking the seat after losing a bid to Sen. Elissa Slotkin last cycle.
Ohio
GOP Sen. Jon Husted is defending his seat against a comeback bid by former Sen. Sherrod Brown, who lost his reelection bid in Ohio’s other Senate seat last cycle. Democrats are hoping Brown’s working-class brand will propel him to victory against Husted, the former lieutenant governor who was appointed to JD Vance’s seat last year after Vance became vice president.
Texas
Texas Attorney General Ken Paxton and state Rep. James Talarico are competing in a closely watched contest in the Lone Star State. Democrats saw their chances of flipping the seat improve after Paxton defeated incumbent GOP Sen. John Cornyn, given Paxton’s history of personal controversies and more conservative positions. But Republicans remain confident in their chances of holding onto the seat, though some concede that the race will be tough — and expensive.
Georgia
GOP Rep. Mike Collins is taking on Democratic Sen. Jon Ossoff in Georgia in a competitive race that was once expected to be the easiest pickup opportunity for Republicans. But a messy Republican primary slowed the launch of Republicans’ general election fight to unseat the first-term senator.
North Carolina
Former Democratic Gov. Roy Cooper and former Republican National Committee Chairman Michael Whatley are jockeying for a seat representing North Carolina in the Senate after GOP Sen. Thom Tillis announced he wouldn’t seek reelection. Democrats see the seat in the Tar Heel State as a key prize, representing their best chance at flipping a seat this cycle.
New Hampshire
Democratic Rep. Chris Pappas and former GOP Sen. John Sununu are running for an open Senate seat in New Hampshire to fill Sen. Jeanne Shaheen’s seat upon her retirement. New Hampshire hasn’t elected a Republican to the Senate since 2010, but Republicans are hopeful about the prospects for Sununu, whose family has been dominant in Granite State politics.
*
House
All 435 House seats are up for election, with 218 as the threshold for the majority. The House is currently very narrowly divided, with 218 Republicans, plus an independent who caucuses with the GOP, and 214 Democrats. Two seats are vacant.
These are the 42 House races to watch:
Arizona’s 1st Congressional District
Republican Jay Feely and Democrat Amish Shah are vying to replace eight-term GOP Rep. David Schweikert, who ran unsuccessfully for governor. Feely, an NFL veteran and former analyst for CBS Sports, initially ran in another district, but he switched at the urging of President Trump. Shah failed to unseat Schweikert in 2024.
Arizona’s 6th Congressional District
Republican Rep. Juan Ciscomani is up against Marine veteran JoAnna Mendoza in the district that stretches from the Tucson-area suburbs down to the southeastern corner of the state along the U.S.-Mexico border.
California’s 13th Congressional District
The seat held by Democratic Rep. Adam Gray is one of the House Republicans’ campaign arm’s top targets. Gray flipped the seat in 2024, narrowly winning by fewer than 200 votes. In 2022, he lost by fewer than 600 votes. In June’s nonpartisan primary, he had a significant advantage over Republican Kevin Lincoln, a Marine veteran.
California’s 22nd Congressional District
GOP Rep. David Valadao is one of two remaining House Republicans in Congress who voted to impeach President Trump in 2021 over the Capitol riot. He is the last one running for reelection, since Washington Rep. Dan Newhouse is retiring. Valadao is running against Democrat Randy Villegas in the newly redrawn district.
California’s 45th Congressional District
Democratic Rep. Derek Tran’s district was redrawn as part of Gov. Gavin Newsom’s redistricting push, making his new district one that Vice President Kamala Harris won by only 4 points. The House Republicans’ campaign arm is backing former Cerritos Mayor Chuong Vo in its effort to target the Orange County-area district.
California’s 48th Congressional District
Republican Jim Desmond and Democrat Marni Von Wilpert are on the ballot to replace outgoing GOP Rep. Darrell Issa in a newly redrawn Southern California district.
Colorado’s 8th Congressional District
GOP Rep. Gabe Evans, who flipped a seat held by a Democrat in 2025, is running for reelection against Democrat Manny Rutinel, a progressive state representative. The district, which is north of Denver, has a sizable Latino population.
Florida’s 14th Congressional District
Democratic Rep. Kathy Castor’s Tampa-area district has been redrawn to be more friendly to Republican, but it is still rated as Lean Democratic. Former state Rep. Mike Beltran won the crowded GOP primary to take on Castor in the fall.
Florida’s 22nd Congressional District
After this district was gerrymandered to be more GOP-friendly, its congresswoman, Democrat Lois Frankel, opted instead to run in the 23rd District. Democrat Pia Dandiya won the August primary, and Republican Casey Askar prevailed in the crowded GOP primary. Both parties’ campaign arms are targeting the Palm Beach County district.
Florida’s 25th Congressional District
Democratic Rep. Jared Moskowitz is running for reelection here, though the Boca Raton-area district’s boundaries were altered to be more favorable to Republicans. Moskowitz faces former Boca Raton Mayor Scott Singer on the ballot.
Iowa’s 1st Congressional District
Democrat Christina Bohannan is trying for a third time to unseat Republican Rep. Mariannette Miller-Meeks. Miller-Meeks has won several close races since 2020.
Iowa’s 2nd Congressional District
Republican Joe Mitchell and Democrat Lindsay James are on the ballot to replace GOP Rep. Ashley Hinson, who is running for Senate.
Iowa’s 3rd Congressional District
GOP Rep. Zach Nunn is defending his seat against Democrat Sarah Trone Garriott. Nunn, who has represented the Des Moines-area district since 2023, won reelection in 2024 by less than 4 points.
Michigan’s 4th Congressional District
Longtime GOP Rep. Bill Huizenga is trying to fend off a challenge from Democrat Sean McCann, a state senator.
Michigan’s 7th Congressional District
GOP Rep. Tom Barrett, who was first elected in 2024, is one of a handful of Republicans who have supported Democratic-led war powers resolutions to rein in President Trump on Iran. He’s facing Democrat William Lawrence, who cofounded the Sunrise Movement and is a former member of the Democratic Socialists of America.
Michigan’s 8th Congressional District
After suspending his campaign, Thomas Smith defeated a Trump-backed candidate to win the GOP primary and take on Democratic Rep. Kristen McDonald Rivet. Though the district elected McDonald Rivet in 2024, it also voted for President Trump.
Michigan’s 10th Congressional District
Republican Michael Bouchard and Democrat Christina Hines are competing for the open seat, which is currently held by GOP Rep. John James, who is running for Michigan governor.
Nebraska’s 2nd Congressional District
Republican Brinker Harding and Democrat Denise Powell are hoping to replace retiring GOP Rep. Don Bacon in the Omaha-area district. Though the seat has been in GOP hands for all but two years in the last three decades, the district has voted for a Democrat in three of the last five presidential elections.
Nevada’s 3rd Congressional District
Video game music composer Marty O’Donnell is hoping to unseat Democratic Rep. Susie Lee in the 3rd District, which touches parts of Las Vegas.
New Hampshire’s 1st Congressional District
Democratic Rep. Chris Pappas opted to run for Senate this year, leaving the swingy seat open. Pappas has held the seat since 2017, but before that, it flipped five times between Republican and Democrats. Democrat Stefany Shaheen, the daughter of retiring Sen. Jeanne Shaheen, will face Republican Anthony DiLorenzo.
New Jersey’s 7th Congressional District
GOP Rep. Tom Kean Jr. is defending his seat against Democrat Rebecca Bennett, after his lengthy absence from Congress earlier this year. Upon his return to work in June, he disclosed he had been diagnosed with depression and was hospitalized for treatment.
New Mexico’s 2nd Congressional District
Marine veteran Greg Cunningham is challenging Democratic Rep. Gabe Vasquez in the district, which spans the southern half of the state and includes part of Albuquerque. Vasquez was elected to the House in 2022, flipping the seat.
New York’s 3rd Congressional District
Democratic Rep. Tom Suozzi is defending his seat against former New York state Rep. Mike LePetri in the Long Island district. The longtime Democratic district flipped Republican in 2022, but after former Rep. George Santos was expelled from Congress, Suozzi won the special election for the seat. He was reelected in 2024, though Mr. Trump won the district.
New York’s 4th Congressional District
In 2024, Democratic Rep. Laura Gillen defeated the Republican incumbent, Rep. Anthony D’Esposito, after he beat her in the race for the open Long Island seat in 2022. She’ll face local tax receiver and GOP candidate Jeanine Driscoll.
New York’s 17th Congressional District
GOP Rep. Mike Lawler has held the lower Hudson Valley seat since 2023, casting himself as a moderate who can work across the aisle. Democrat Cait Conley, a national security expert and Army combat veteran, moved to the district shortly before announcing her candidacy, though she grew up in the region. Harris narrowly won the district against Mr. Trump in 2024.
New York’s 19th Congressional District
Democratic Rep. Josh Riley is trying for a second term in a district that has been competitive. GOP state Sen. Peter Oberacker is his opponent.
North Carolina’s 1st Congressional District
The race is a rematch between Republican Laurie Buckhout and Democratic Rep. Don Davis. Davis is facing a tough reelection bid in a district that has leaned further to the right after several rounds of gerrymandering by state Republicans.
North Carolina’s 11th Congressional District
