Key Points

  • CNN projects Democrats have won more than 250 seats in the House of Representatives, a net gain of around 40 — their biggest House majority since 2008.
  • At least 30 Republican incumbents have been ousted, from swing districts to long-held GOP strongholds.
  • Democrats have won or lead in 259 districts; if those leads hold, the final total could reach 260, their biggest majority since 1991.
  • The 250th seat came in Arizona’s 1st District, where Democrat Amish Shah flipped the seat — the party’s 40th pickup of the cycle.
  • 218 seats are needed for a House majority; the new Congress convenes in January.

Democrats have cleared 250 seats in the House of Representatives, CNN projects, giving the party its biggest House majority since 2008 and a sweeping mandate from Tuesday’s midterm vote.

What happened: Democrats pass 250 seats in the House

Democrats have passed 250 seats in the House of Representatives, CNN’s Decision Desk projected on Thursday afternoon, turning Tuesday’s midterm vote into one of the biggest House victories in modern American politics. The party has now won more than 250 seats, with a net gain of around 40 on the night, and the count is still going.

The milestone seat came in Arizona’s 1st District, where Democrat Amish Shah was projected to defeat his Republican opponent. That win was the party’s 40th pickup of the cycle and took its projected total to 250. By Thursday afternoon, the Associated Press had called 253 races for Democrats and 155 for Republicans, with 27 races still to be decided, according to the New York Post.

The scale of the defeat for Republicans is visible in the incumbents who lost. At least 30 Republican incumbents have been ousted, CNN reported, with losses spread across competitive swing districts and districts Republicans had held for decades. Among the heaviest losses was Virginia’s 1st District, where Democrat Shannon Taylor unseated Representative Rob Wittman, who had held the seat since 2007. The Associated Press called the race for Taylor on Thursday after a district Republicans had held for nearly half a century changed hands.

Democrats also took control of the Senate in Tuesday’s vote, completing a clean sweep of Congress. The party’s night included historic firsts, among them Abdul El-Sayed’s win in Michigan, making him the first Muslim elected to the United States Senate. The scale of the result has been felt across the Republican Party, and President Donald Trump has admitted the war in Iran hurt his party at the ballot box, saying it was “a part of it”.

Why it matters: the biggest majority in nearly two decades

A House majority of more than 250 seats is the largest any party has held since 2008, when Democrats won 257 seats alongside Barack Obama’s first presidential victory. It is also already bigger than any Republican House majority since the Great Depression — the Republicans’ high point in that period was 247 seats after the 2014 election.

The final number could be larger still. Democrats have won or hold leads in 259 districts, and if those margins hold they would finish with a net gain of 44 seats. If the total reaches 260, it would be the Democrats’ biggest House majority since the 1991-93 Congress, when the party held 267 seats at the tail end of decades of dominance in the chamber. It would also mean the party controls 60 percent of all 435 House seats.

The size of the majority matters because it decides what the new Congress can do. With a margin of more than 30 seats above the 218 needed for control, Democratic leaders can lose votes from their own members and still pass legislation. It also gives the party wide power to open investigations, demand documents and call hearings into the Trump administration — powers the party’s leaders have said they intend to use from January.

For Republicans, the result is a reckoning. The party entered the election holding 220 House seats and is heading for a loss of more than 40. The defeat has already set off open blame inside the party over the Iran war, the cost of living and the party’s ties to Israel, with senior figures publicly arguing over what went wrong.

What happens next: counting continues, then the new Congress

Counting continues in the remaining races, with votes still being tallied in key districts in Maine, Montana, Florida and Alaska, among other states. The final size of the Democratic majority will only be known once every race is decided, and two Senate contests — in Alaska and Mississippi — also remain uncalled.

House Democratic Leader Hakeem Jeffries has said his party will finish with at least 255 seats. The new Congress convenes in January, when Democrats will take the Speaker’s gavel and the chairmanships of every House committee. Before then, the outgoing Republican-led House must still pass government funding, and the lame-duck session is expected to be tense after the scale of the defeat.

The new majority will also shape the road to 2028. A Democratic House with a wide majority can block the administration’s agenda, force votes on the issues that drove the midterm result, and set the terms of the next presidential race. How the party uses a majority of this size — the first of its kind in nearly twenty years — will be the defining question of the next two years.
