US midterm elections: Democrats seize both chambers of Congress as blue wave breaches Republican strongholds

New Delhi: Democrats have won control of both chambers of the United States Congress, breaking through Republican strongholds in an election that sharply reduces the president, Donald Trump’s, room to advance his domestic agenda. The Tuesday vote delivered Republican defeats across Senate, House and governor’s races, with frustration over living costs and the war with Iran featuring prominently in voters’ decisions.

Results reported on Wednesday showed Democrats capturing seven Republican-held Senate seats, including in Texas, Kansas and South Carolina, while securing a majority in the House of Representatives. Counting continued in individual constituencies, leaving the final size of their majorities unsettled even as control of Congress was decided.

The outcome sets up divided government for the remaining two years of Trump’s presidency, giving the opposition greater power over legislation, spending and scrutiny of his administration. Trump accepted the result and congratulated Democrats, although his subsequent comments signalled that cooperation would come alongside confrontation.

Senate breakthrough reaches deep into Republican territory

Democrats entered the election needing a net gain of four seats to overturn the Republicans’ 53–47 Senate advantage. They exceeded that requirement by flipping seats in Iowa, Kansas, Maine, North Carolina, Ohio, South Carolina and Texas, according to Ballotpedia’s results summary.

In Texas, the Democratic state legislator, James Talarico, defeated the Republican attorney general, Ken Paxton, ending his party’s long exclusion from the state’s Senate seats. Paxton had defeated the incumbent, John Cornyn, in the Republican primary runoff, making the general election defeat a setback for a candidate Trump had backed.

Kansas produced another significant reversal, with the Methodist pastor, Adam Hamilton, defeating the incumbent Republican senator, Roger Marshall. Hamilton became the first Democrat elected to the Senate from Kansas since 1932, campaigning on household expenses, healthcare, tariffs and dissatisfaction with political division.

In South Carolina, the Democrat and paediatrician, Annie Andrews, defeated the Republican incumbent, Darline Graham, while the former North Carolina governor, Roy Cooper, beat Michael Whatley in the neighbouring state. The victories demonstrated that the Democratic advance extended beyond the small group of closely divided states that usually determine congressional control.

The former Democratic senator, Sherrod Brown, won Ohio’s special Senate election against Jon Husted, reclaiming a place in the chamber after his earlier defeat in 2024. In Iowa, Josh Turek defeated Ashley Hinson, while Maine’s Troy Jackson unseated the veteran Republican senator, Susan Collins.

Democrats also protected important seats, with Jon Ossoff winning re-election in Georgia and Chris Pappas winning New Hampshire’s contest to succeed the retiring Jeanne Shaheen. Those victories prevented Republican gains from offsetting the Democratic breakthroughs elsewhere.

House changes hands as voter discontent spreads

In the House, Democrats combined the defence of vulnerable incumbents with gains in competitive districts and constituencies previously considered more secure for Republicans. Roll Call’s account of the House results described advances across both battleground territory and more strongly Republican areas, including gains supported by Latino voters in Texas.

Republican losses included Tom Kean in New Jersey and Ryan Mackenzie, Scott Perry and Rob Bresnahan in Pennsylvania. Democrats also captured open seats in North Carolina and Kentucky, illustrating the geographical breadth of the shift.

The result puts the House Democratic leader, Hakeem Jeffries, in line to become the chamber’s first Black speaker, subject to the formal election by its members. It also gives his party control of committees with the authority to investigate the administration and compel testimony.

Voter dissatisfaction extended beyond individual candidates, with Reuters reporting that approximately half of those surveyed in national exit polling viewed the election as an opportunity to register opposition to Trump. Around three-quarters described themselves as angry or dissatisfied with the country’s direction, underlining the difficult political environment Republicans faced.
