There are 16 races that ABC News rates as Tossup going into Election Day.

By Lauren Peller, John Parkinson 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.
