当选民在11月3日前往投票站时，众议院的所有435个席位都在投票中。但纵观整个政治版图，美国广播公司新闻频道（ABC News）估计有16场比赛的结果预计将最终揭晓，并将对决定第120届国会众议院的权力平衡至关重要。
民主党必须至少获得三个席位才能控制局面。
以下是美国广播公司新闻频道评为最佳的比赛：
阿拉巴马州2：现任民主党人肖马里数字与共和党人瑞德马克斯
在这个新划定的地区，在一场竞争激烈的比赛中，图茨面对的是州代表马克斯。在最高法院允许阿拉巴马州恢复联邦法院此前阻止的2023年国会地图后，该地区被重新划分。数字指望黑人选民的高投票率，他们占该地区投票年龄人口的40%。唐纳德·特朗普总统10月2日在莫比尔集会，敦促选民支持马克斯。特朗普将在2024年以14个百分点的优势拿下新区。
科罗拉多5：现任共和党人杰夫·克兰克vs民主党人杰西卡·克林
克兰克与克林展开了激烈的竞争，克林是一名退伍军人，也是当时第二绅士道格·艾姆霍夫的前参谋长。该地区包括科罗拉多斯普林斯和几乎整个埃尔帕索县，在过去的三个总统选举周期中更加左倾。然而，特朗普在2024年以大约9个点的优势赢得了这个军事重地。伊朗战争是这场竞选中的一个关键问题。克兰克支持战争，但认为特朗普应该寻求国会的批准。
佛罗里达州14：现任民主党人凯西·卡斯特vs共和党人迈克·贝尔特兰
Castor是一名10届任期的现任者，正在与特朗普支持的前出庭律师Beltran对抗。在佛罗里达州的立法机构重新划定这个地区后，这个席位变得更加竞争激烈，使Castor处于守势。
佛罗里达州22：开放的民主党人皮娅丹迪亚与共和党人凯西阿斯卡尔
佛罗里达州新划定的选区横跨棕榈滩和布劳沃德县的部分地区以及那不勒斯市，这场斗争让两位政治新人进入了战场：海军陆战队老兵阿斯卡尔（Askar）与前教师、美国教育部官员丹迪亚（Dandiya）。
爱荷华州2：开放的民主党人林赛·詹姆斯vs共和党人乔·米切尔
随着现任国会女议员阿什利·辛森竞选参议员，这个鹰眼州历史上的红色众议院席位现在可供争夺。詹姆斯是一名州议员兼牧师，他正在与米切尔竞选，米切尔是一名29岁的游说者，曾在特朗普的过渡团队工作过。特朗普在2024年以10个百分点的优势赢得了这一地区，但伊朗战争的经济影响和对这一以农业为主的地区的关税使这场比赛变得很有竞争力。
肯塔基州6：开放的民主党人扎克·德姆博主场迎战共和党人拉尔夫·阿尔瓦拉多
共和党众议员安迪·巴尔（Andy Barr）试图填补米奇·麦康奈尔（Mitch McConnell）长期占据的参议院席位，这使得他在肯塔基州的众议院席位空缺。德姆博，前联邦检察官和海军军法署官员，面对阿尔瓦拉多，医生和前州参议员。这个选区过去更具竞争力，但2022年的重划使它近年来对共和党更友好——尽管巴尔自2012年当选以来一直是民主党的目标。
密歇根州4：现任共和党人比尔·胡伊曾加对民主党人肖恩·麦卡恩
自2011年以来一直在国会任职的Huizenga正在受到州参议员McCann的挑战。Huizenga确实具有在任优势，并在2024年大幅超过特朗普，但他的竞争似乎正在加剧，因为许多民意调查机构预计总统的政党将面临糟糕的政治环境。
密歇根7：现任共和党人汤姆·巴雷特对民主党人威廉·劳伦斯
第一任国会议员、前陆军直升机飞行员巴雷特（Barrett）曾多次投票限制特朗普在伊朗的战争权力，他希望保住自己的席位，并击败进步候选人劳伦斯（Lawrence），后者是进步日出运动的联合创始人。尽管分裂，特朗普一直在竞选中支持巴雷特在竞争激烈的摇摆选区连任，民主党人埃利萨·斯洛特金在2018年击败了一名共和党人，在她最终赢得2024年参议院竞选之前翻转了这个席位。
密歇根州10：开放的民主党克里斯蒂娜海因斯与共和党迈克布沙尔
随着众议员约翰·詹姆斯竞选密歇根州的下一任州长，他在底特律北部郊区的空缺席位可供争夺。这场斗争是在前检察官海因斯和退伍军人布沙尔之间展开的。特朗普在2024年以超过6个百分点的优势赢得了这一地区。
蒙大拿州1：开放的民主党人山姆福斯特格与共和党人亚伦弗林特
众议员瑞安·津克（Ryan Zinke）的退休使得蒙大拿州的席位空缺，共和党人没有任何在职优势。弗林特是一名退伍军人和保守派电台节目主持人，他的竞争对手是工会领袖和荒地消防员空降消防员福斯特格。特朗普在2024年以近12个点的优势赢得了这个覆盖蒙大拿州西部的选区。
纽约17：现任共和党人迈克·劳勒vs民主党人凯特·康利
劳勒是这一轮在卡玛拉·哈里斯选区竞选连任的两名共和党人之一，其他六人选择反对在众议院连任。劳勒自2022年以来一直保持这一席位处于蓝色状态，在2024年领先特朗普2．8%。劳勒在特朗普税收法案谈判中获得了州和地方税（盐）减免，正在与陆军战斗老兵康利竞选。
俄亥俄州7：现任共和党人马克斯·米勒vs民主党人布莱恩·波因德克斯特
米勒的连任竞选因其前妻艾米丽·莫雷诺（Emily Moreno）受到家庭暴力指控而受阻，艾米丽·莫雷诺是俄亥俄州共和党参议员伯尼·莫雷诺的女儿。特朗普的前助手米勒断然否认有不当行为，没有受到任何犯罪指控，并拒绝退出竞选，尽管共和党人普遍呼吁。特朗普去年夏天没有呼吁米勒退出，称这种情况“令人难过”。他受到了工会组织者和钢铁工人Poindexter的挑战。
宾夕法尼亚州1：现任共和党人布莱恩·菲茨帕特里克vs民主党人鲍勃·哈维
曾任美国联邦调查局特工的五届在任共和党人Fitzpatrick是另一位竞选连任的共和党人，Harris在2024年赢得了该地区的选举。Fitzpatrick在政策问题上多次与总统决裂，是投票反对他的巨额税收和政策法案的两个众议院共和党人人之一。他已经在众议院确立了温和派的地位，这有助于提高他在竞争激烈的选区的选举表现，该选区包括巴克斯县和蒙哥马利县。哈维自2020年以来一直担任巴克斯县专员。
德克萨斯州15：民主党鲍比·普利多vs现任共和党莫妮卡·德拉克鲁兹
德拉克鲁兹于2022年首次当选，她正在寻求保住自己在南德克萨斯州的席位，该地区近80%是拉丁裔。重划选区将第15选区扩大到了伊达尔戈县，并将她的一些共和党选民转移到了邻近的选区。拉丁美洲获奖歌手Pulido正在挑战De La Cruz，这场比赛可能会考验Trump在拉丁美洲选民中的地位。
得克萨斯州35：开放-民主党约翰尼加西亚与共和党卡洛斯德拉克鲁兹
这个东圣安东尼奥的席位以前由民主党众议员格雷格·卡萨尔担任，在国会进步党团主席因共和党控制的立法机构发起的重新划分选区而改变选区后，这个席位是开放的。副警长加西亚希望保持该地区的蓝色，并与特朗普支持的德拉克鲁兹竞选，德拉克鲁兹是一名空军老兵，也是众议员莫妮卡·德拉克鲁兹的兄弟。
弗吉尼亚1号：我共和党人罗布·惠特曼vs。民主党人莎农·泰勒
在北弗吉尼亚和中部半岛，10届共和党人惠特曼正与亨利科县最高检察官泰勒争夺自己的席位。这是全国少数几个卡玛拉·哈里斯在2024年胜过乔·拜登（Joe Biden）的地区之一，表明该地区正在向左转。
These House races could determine which party is in control in the next Congress
All 435 seats in the House of Representatives are on the ballot when voters head to the polls on Nov． 3． But spread across the political map， there are 16 races that ABC News rates as tossup in which the outcomes are expected to come down to the wire and will be crucial to determining the balance of power in the House for the 120th Congress．
Democrats must net at least a three-seat gain to take control．
Here are the races that ABC News rates as Tossup：
Alabama 2： Incumbent Democrat Shomari Figures vs． Republican Rhett Marques
In this newly drawn district， Figures faces Marques， a state representative， in a competitive race． The district was redrawn after the Supreme Court allowed Alabama to reinstate a 2023 congressional map that a federal court had previously blocked． Figures is counting on strong turnout among Black voters， who make up about 40% of the district’s voting-age population． President Donald Trump rallied in Mobile on Oct． 2 and urged voters to back Marques． Trump would have carried the new district by 14 points in 2024．
Colorado 5： Incumbent Republican Jeff Crank vs． Democrat Jessica Killin
Crank is locked in a tight race against Killin， an Army veteran and former chief of staff for then-second gentleman Doug Emhoff． The district， which includes Colorado Springs and nearly all of El Paso County， has leaned more left over the past three presidential cycles． However， Trump won this military-heavy district by about 9 points in 2024． The Iran war is a key issue in this race． Crank supports the war but believes Trump should have sought congressional approval．
Florida 14： Incumbent Democrat Kathy Castor vs． Republican Mike Beltran
Castor， a 10-term incumbent， is facing off against Trump-endorsed former trial lawyer Beltran． The seat became more competitive after Florida’s legislature redrew this district， putting Castor on the defensive．
Florida 22： Open -- Democrat Pia Dandiya vs． Republican Casey Askar
The battle for Florida’s newly drawn district spanning parts of Palm Beach and Broward counties and the city of Naples puts two political newcomers in the ring： Marine Corps veteran Askar against former teacher and U．S． Education Department official Dandiya．
Iowa 2： Open -- Democrat Lindsey James vs． Republican Joe Mitchell
As incumbent congresswoman Ashley Hinson runs for Senate， this historically red House seat in the Hawkeye State is now up for grabs． James， a state representative and chaplain， is running against Mitchell， a 29-year-old lobbyist and former state representative who worked on Trump’s transition team． Trump won this district by 10 points in 2024， but the economic impacts from the Iran war and tariffs on this agriculture-heavy district have made this race competitive．
Kentucky 6： Open -- Democrat Zach Dembo vs． Republican Ralph Alvarado
GOP Rep． Andy Barr’s bid to fill Mitch McConnell’s long-held Senate seat leaves his Kentucky House seat open． Dembo， a former federal prosecutor and Navy JAG officer， faces Alvarado， a physician and former state senator． This district used to be more competitive， but redistricting in 2022 has made it friendlier to Republicans in recent years – though Barr was a consistent Democratic target since he was elected in 2012．
Michigan 4： Incumbent Republican Bill Huizenga vs． Democrat Sean McCann
Huizenga， who has served in Congress since 2011， is being challenged by McCann， a state senator． Huizenga does have incumbency advantage and outperformed Trump substantively in 2024， but his race appears to be tightening as many pollsters anticipate a sour political environment for the president’s party．
Michigan 7： Incumbent Republican Tom Barrett vs． Democrat William Lawrence
First-term congressman and former Army helicopter pilot Barrett， who has repeatedly bucked Trump by voting to limit his war powers in Iran， hopes to keep his seat and defeat progressive candidate Lawrence， a co-founder of the progressive Sunrise Movement． Despite the split， Trump has campaigned in favor of Barrett’s reelection in the competitive swing district， where Democrat Elissa Slotkin beat a Republican in 2018 to flip this seat before she ultimately won a bid for Senate in 2024．
Michigan 10： Open -- Democrat Christina Hines vs． Republican Mike Bouchard
As Rep． John James runs to be Michigan’s next governor， his open seat in Detroit＇s northern suburbs is up for grabs． The battle is between Hines， a former prosecutor， and Bouchard， an Army veteran． Trump carried this district by more than six points in 2024．
Montana 1： Open -- Democrat Sam Forstag vs． Republican Aaron Flint
Rep． Ryan Zinke’s retirement has left this Montana seat open with no incumbency advantage for Republicans． Flint， an Army veteran and conservative radio show host， is running against Forstag， a union leader and wildland firefighter smokejumper． Trump won this district covering western Montana by nearly 12 points in 2024．
New York 17： Incumbent Republican Mike Lawler vs． Democrat Cait Conley
Lawler is one of two Republicans running for reelection in Kamala Harris-won districts this cycle -- six others opted against another term in the House． Lawler has kept this seat in a blue state since 2022， outperforming Trump in 2024 by 2．8%． Lawler， who secured State and Local Tax （SALT） deductions during the Trump tax bill negotiations， is running against Conley， an Army combat veteran．
Ohio 7： Incumbent Republican Max Miller vs． Democrat Brian Poindexter
Miller’s reelection bid has been hampered by allegations of domestic assault against his ex-wife Emily Moreno， the daughter of Ohio Republican Sen． Bernie Moreno． Miller， a former Trump aide， has flatly denied wrongdoing and has not been charged with any crimes and refused to drop out of the race despite widespread calls from Republicans． Trump stopped short of calling on Miller to withdraw last summer， calling the situation ＂sad．” He’s being challenged by Poindexter， a union organizer and ironworker．
Pennsylvania 1： Incumbent Republican Brian Fitzpatrick vs． Democrat Bob Harvie
Five-term incumbent Fitzpatrick， a former FBI agent， is the other Republican running for re-election in a district that Harris won in 2024． Fitzpatrick has repeatedly broken with the president on policy issues and was one of two House Republicans who voted against his mega tax and policy bill． He has established himself as a moderate in the House， helping boost his electoral performance in the competitive district， which includes Bucks County and Montgomery County． Harvie， has served as a Bucks County commissioner since 2020．
Texas 15： Democrat Bobby Pulido vs． incumbent Republican Monica De La Cruz
De La Cruz， who was first elected in 2022， is seeking to keep her seat in a South Texas district that is nearly 80% Latino． Redistricting expanded the 15th into Hidalgo County and shifted some of her GOP voters into neighboring districts． Pulido， a Latin Grammy-winning Tejano singer， is challenging De La Cruz in a race that could test Trump’s standing with Latino voters．
Texas 35： Open -- Democrat Johnny Garcia vs． Republican Carlos De La Cruz
This East San Antonio seat， previously held by Democratic Rep． Greg Casar， is open after the chair of the Congressional Progressive Caucus changed districts because of redistricting initiated by the Republican-controlled legislature． Garcia， a deputy sheriff， hopes to keep the district blue and is running against Trump-endorsed De La Cruz， an Air Force veteran and brother of Rep． Monica De La Cruz．
Virginia 1： Incumbent Republican Rob Wittman vs．Democrat Shannon Taylor
In North Virginia and the Middle Peninsula， 10-term Republican Wittman is battling to keep his seat against Taylor， Henrico County’s top prosecutor． It is one of a few districts across the country where Kamala Harris in 2024 outperformed Joe Biden in 2020， suggesting the district is trending left．
