Live House election results for 2024 races

State Sen. Sarah McBride, a Democrat, won Delaware's only congressional district, CBS News projected. She will become the first openly transgender member of Congress and will replace Democratic Rep. Lisa Blunt Rochester, who was elected to the Senate. 

Polls are closed in Montana, Nevada and Utah as of 10 p.m. Eastern Time. 

The most competitive races in those states are:

Montana's 1st Congressional District, where Democrat Monica Tranel is once again challenging Republican Rep. Ryan Zinke. The nonpartisan Cook Political Report considers the race lean Republican. 

Nevada's 3rd Congressional District, where Democratic Rep. Susie Lee is defending her seat against libertarian-leaning Republican Drew Johnson. The race is considered lean Democrat. 

A Pennsylvania judge has ruled that polls in Northampton County will not be kept open late, despite some voters waiting in line for hours on Tuesday. Lines at a polling place near Lehigh University took more than five hours at times. 

Polls in the state closed at 8 p.m. Eastern Time. The judge ruled that those already in line at 8 p.m. will be allowed to cast their votes, in keeping with state law. 

The county is part of the state's 7th Congressional District, where Democratic Rep. Susan Wild is fighting for a fourth term against Republican Ryan Mackenzie, a state legislator.

Polls have also closed in Arkansas, Arizona, Colorado, Iowa, parts of Kansas, Louisiana, parts of Michigan, Minnesota, Nebraska, New Mexico, New York, parts of North Dakota and South Dakota, most of Texas, Wisconsin and Wyoming as of 9 p.m. Eastern Time. 

Reminder that if you're in line to vote when polls close in your state, you have the right to vote if you stay in line. 

There are two competitive seats in Arizona, including the 1st District and the 6th District. Colorado's 8th District, Iowa's 1st District and 3rd District, Nebraska's 2nd District, New Mexico's 2nd District and Wisconsin's 3rd District are also considered key House races in determining who will win the majority. 

Michigan has two open seats that are competitive — the 7th Congressional District, where Democratic Rep. Elissa Slotkin is giving up the seat to run for the Senate, and the 8th Congressional District, where the seat is being vacated by Democratic Rep. Dan Kildee. 

New York has a number of races that will be key to determining the House majority. Read more here about the New York races. 

As of 8 p.m. Eastern Time, polls have closed in Alabama, Connecticut, Delaware, Washington, D.C., parts of Florida, Illinois, Maine, Maryland, Massachusetts, Mississippi, Missouri, New Hampshire, New Jersey, Oklahoma, Pennsylvania, Rhode Island and Tennessee. 

There are competitive races in Maine's 2nd District, where Democratic Rep. Jared Golden is facing Republican candidate Austin Theriault, a former NASCAR driver. It's a district that has voted for former President Donald Trump twice. 

In Pennsylvania, there are three districts that are competitive, including the 7th District, the 8th District and the 10th District. Two are currently held by Democrats, the other is held by Republicans. 

Polls have closed in another three states as of 7:30 p.m. Eastern Time. 

The race between Democratic Rep. Don Davis and Republican candidate Laurie Buckhout in North Carolina's 1st Congressional District is considered a toss-up by the nonpartisan Cook Political Report. 

Republicans are also trying to unseat Democratic incumbents in two competitive races in Ohio's 9th Congressional District and 13th Congressional District. 

Rep. Dan Newhouse of Washington and Rep. David Valadao of California are the only two remaining Republicans in the House who voted to impeach former President Donald Trump in 2021 over the riot at the U.S. Capitol. 

Ten Republicans joined all Democrats in voting to impeach Trump. The eight other Republicans have since retired or lost their primaries in 2022. 

Newhouse is facing a Trump-backed Republican opponent, Jerrod Sessler, in Washington's 4th District. In his endorsement of Sessler, Trump called Newhouse "weak and pathetic" and said he voted to impeach him "for no reason." 

Valadao is also locked in a tight race against Democrat Rudy Salas in California's 22nd District. Valadao beat Salas by 3 percentage points in the 2022 midterm elections. 

As of 7 p.m. Eastern Time, polls have closed in Georgia, Indiana, Kentucky, South Carolina, Vermont and Virginia. Reminder that if you're in line to vote when polls close in your state, you have the right to vote if you stay in line. A few polling locations will stay open late in Georgia due to threats that disrupted voting earlier Tuesday. 

Georgia, a battleground state, will play an important role in the presidential race, but two districts in Virginia — the 2nd Congressional District and the 7th Congressional District — will affect which party controls the House. 

Democratic Rep. Abigail Spanberger is vacating the 7th District seat to run for Virginia governor in 2025. The race between Democrat Eugene Vindman and Republican Derrick Anderson is considered a toss-up by the nonpartisan Cook Political Report. 

Republican Rep. Jen Kiggans is in a tough race against her Democratic challenger Missy Cotter Smasal in Virginia's 2nd District. 

California has a number of competitive races that will help determine who wins control of the House, including five that are considered toss-ups by the Cook Political Report. 

• California's 13th District: Republican Rep. John Duarte narrowly beat his Democratic challenger Adam Gray in 2022 in one of the closest races that year. It's a rematch between the two this year. The race is considered a toss-up. 
• California's 22nd District: Republican Rep. David Valadao and Democrat Rudy Salas are also expected to have a close rematch in what's also considered a toss-up race. 
• California's 27th District: Republican Rep. Mike Garcia is running against Democrat George Whitesides, the former chief of staff of NASA during the Obama administration and former CEO of Virgin Galactic, in another race that's considered a toss-up. In 2020, Garcia won the seat in a special election, becoming the first Republican to flip a California seat since 1998. 
• California's 41st District: Longtime Republican Rep. Ken Calvert is running against Democrat Will Rollins, a former federal prosecutor. Calvert won by less than 5 percentage points in 2022 and this year's race is considered a toss-up. 
• California's 45th District: Republican Rep. Michelle Steel is also running in a race that's considered a toss-up against Democrat Derek Tran, a lawyer and veteran. Steel won her 2022 race by almost 5 percentage points. 
• California's 47th District: Republican Scott Baugh is competing against Democrat David Min for the district's open seat. The race is considered lean Democrat. The seat is currently held by Democratic Rep. Katie Porter, who lost her bid for California's open Senate seat against Democratic Rep. Adam Schiff. 
• California's 49th District: Democratic Rep. Rep. Mike Levin is running for reelection against Republican Matt Gunderson, a business owner. The race is considered lean Democrat. 

Half a dozen House races in New York, though not a battleground state, are expected to play an important role in determining control of the lower chamber. The six seats, five of which are held by Republicans, helped decide the House majority in 2022. 

• New York's 1st District: Rep. Nick LaLota, a first-term Republican, is facing a competitive race against moderate Democrat John Avlon, a former CNN anchor. 
• New York's 4th District: Rep. Anthony D'Esposito, a first-term Republican, is in a tough race against Democrat Laura Gillen, a former Hempstead Town supervisor. He is one of three House Republicans whose races are considered lean Democrat by the Cook Political Report.
• New York's 17th District: Rep. Mike Lawler, a first-term Republican, narrowly won his seat in 2022 when he defeated Sean Patrick Maloney, who led the House Democrats' campaign arm. It was a major loss for Democrats. This time, Lawler is running against former Democratic Rep. Mondaire Jones. 
• New York's 18th District: Rep. Pat Ryan was the only Democrat in New York's battleground districts to win in 2022. He's running against Republican Alison Esposito, a former New York City police officer. 
• New York's 19th District: Rep. Marc Molinaro, a first-term Republican, is in a rematch with his Democratic opponent Josh Riley, whom he narrowly beat in 2022. 
• New York's 22nd District: Rep. Brandon Williams, another first-term Republican, is one of three House Republicans whose races are considered lean Democrat by the Cook Political Report. Williams is facing moderate Democrat John Mannion. 

House Minority Leader Hakeem Jeffries of New York could make history as the first Black speaker if Democrats win the majority. 

It wouldn't be the first time he's made history. Jeffries became the first Black lawmaker to lead a party in Congress when he was elected minority leader in January 2023, succeeding former House Speaker Nancy Pelosi as the top Democrat in the lower chamber. His election also made him the first House Democratic leader to be born after the end of World War II. 

Jeffries was first elected to Congress in 2012. 

House Republicans will hold leadership elections on Nov. 13 after Congress returns from recess. It's a quick turnaround because sluggish returns from California and races that are too close to call or are contested could blur the picture of which party has the majority on Nov. 13. 

If Republicans lose control of the House, there could be a shakeup in GOP leadership. It's unclear if House Speaker Mike Johnson of Louisiana would run for minority leader or if anyone would challenge him. 

House Democrats haven't said when they'll hold their leadership elections.

Republicans took back control of the House in the 2022 midterm elections after four years of Democratic rule. But GOP infighting has made it difficult to govern with a razor-thin majority amid early retirements and the expulsion of Rep. George Santos, whose seat was later picked up by a Democrat. 

In January 2023, former House Speaker Kevin McCarthy of California finally won the speaker's gavel after 15 ballots amid a prolonged — and public — fight with conservatives who demanded concessions, foreshadowing the limits of his power over a fractured party.

His deal with far-right Republicans to allow a single member to trigger a no-confidence vote to remove the speaker came back to haunt him nine months later after he relied on the votes of House Democrats to temporarily avert a government shutdown. Eight Republicans voted with all Democrats to remove McCarthy, making it the first time in U.S. history a House speaker was ousted by such a motion. 

Speaker Mike Johnson of Louisiana succeeded McCarthy after three weeks of chaos caused by the GOP's inability to coalesce around a candidate. Though Johnson has faced similar issues as McCarthy and has had to rely on Democratic votes to pass legislation, he has survived in the role longer than his predecessor. Democrats stepped in to rescue Johnson from an ouster attempt in May. 

The last time control of the House flipped in a presidential election year was 1952. Republicans won the House and Dwight D. Eisenhower was elected to his first term in the White House. 

Of the 435 House seats on the ballot, about 40 are seen as competitive, according to the Cook Political Report, a nonpartisan election analysis site that considers 22 of those races toss-ups. Of those 22 seats, 10 are held by Democrats and 12 by Republicans. Of the other 21 competitive seats, 13 are lean Democrat and eight are lean Republican. 

Republicans currently have 220 seats. Democrats have 212. There are three vacancies due to the deaths of Rep. Sheila Jackson, a Texas Democrat, and Rep. Bill Pascrell Jr., a New Jersey Democrat, and the early retirement of Rep. Mike Gallagher, a Wisconsin Republican. 

For Democrats to take control of the chamber they'd have to hold on to their 212 seats and the two vacancies from deaths, as well as pick up four seats. 

It's unlikely to be that easy, however. Redrawn congressional maps in North Carolina mean three seats held by Democrats are poised to be easily won by Republicans.

But the swing toward Republicans is blunted in part by redrawn congressional districts in Louisiana and Alabama that are likely to be won by Democrats under the new lines.
