US midterms explained: what is at stake on Tuesday, and when India will know the result
Americans vote on 3 November for all 435 seats in the House of Representatives, 35 Senate seats and 36 governors. What each party needs, the races that could decide it, why the count may take days, and why it matters beyond Washington.
The short answer
The midterms fall halfway through a president's four-year term. On Tuesday 3 November 2026 Americans elect the whole House of Representatives, 35 of the 100 senators and 36 state governors. Republicans hold the House 218 to 214 and the Senate 53 to 47, so Democrats need only a handful of House seats but a net gain of four Senate seats to take control. Polls close between 4:30 am and 11:30 am IST on Wednesday 4 November. Some races may be called that day, but close contests and late postal ballots can push the final picture back by days or weeks. If Democrats win either chamber, they can block much of Donald Trump's agenda for his last two years.
What are the midterms?
They are the elections held halfway through a president’s term. A US president is elected for four years, but the whole House of Representatives faces the voters every two years and a third of the Senate does too. Donald Trump began his second term in January 2025, so this vote comes at the midpoint, and he is not on the ballot.
On Tuesday 3 November Americans will choose all 435 members of the House, 35 senators and 36 state governors. The Senate count is higher than the usual 33 because there are special elections in Florida and Ohio, for seats vacated when Marco Rubio became secretary of state and JD Vance became vice-president. Below them, 6,139 seats in state legislatures are being filled in 88 of the country’s 99 legislative chambers.
What does each party need?
Republicans control both chambers, but by thin margins. In the House they hold 218 seats to the Democrats’ 214, with one independent and two vacancies. A majority is 218, so Democrats need to gain only a handful of seats to take over, and Republicans can afford to lose very few.
The Senate is harder for Democrats. Republicans hold it 53 to 47, counting two independents who vote with the Democrats. Democrats need a net gain of four seats to reach 51. A 50-50 split would leave Republicans in charge, because Vice-President Vance casts the deciding vote in a tie.
The two chambers at stake on 3 November
Which races could decide it?
About ten Senate contests are seen as close. Democrats are trying to take Republican seats in Texas, where James Talarico faces Ken Paxton; in Ohio, where former senator Sherrod Brown is challenging Jon Husted; in Maine, where Susan Collins is defending her seat against Troy Jackson; and in Iowa and Alaska, where Ashley Hinson faces Josh Turek and Mary Peltola is up against Senator Dan Sullivan. In North Carolina, former governor Roy Cooper takes on Michael Whatley for the seat vacated by Thom Tillis.
Republicans, in turn, hope to win Michigan, where the Democratic senator Gary Peters is retiring. Their candidate, Mike Rogers, got an unexpected boost on Sunday when Haley Stevens, who lost the Democratic primary to Abdul El-Sayed, endorsed him across party lines.
Among the governors’ races, Ohio’s pits the Indian-American Republican Vivek Ramaswamy against Amy Acton, and Texas Governor Greg Abbott faces Gina Hinojosa. House races are harder to call one by one, and redrawn district maps in several states have added to the uncertainty.
Which way are things leaning?
Polls have favoured the Democrats for weeks. The final New York Times/Siena survey before the vote put Democrats ahead by 52% to 41% among likely voters on the question of which party they would back for Congress, and put Trump’s approval at 36%, his lowest in that poll. Voters in those surveys were unhappy about prices and the war with Iran.
Polls are not results, though, and turnout will decide much. More than 52 million Americans had already voted by Sunday, in person or by post. The campaign is also the most expensive midterm yet: spending for the 2025-26 cycle is expected to reach about $12 billion, against a previous midterm record of $8.9 billion in 2022.
When will we know?
Polls start closing at 4:30 am IST on Wednesday 4 November, which is 6 pm on Tuesday on the US east coast. The big battleground closings follow over the next few hours: Georgia at 5:30 am IST, North Carolina and Ohio at 6 am, and Michigan, Texas and Maine at 6:30 am. California closes at 9:30 am IST, Hawaii and most of Alaska at 10:30 am, and the last polling places, in Alaska’s western Aleutian Islands, at 11:30 am.
Some races will be called on Wednesday. Control of the House may take longer. California and Oregon count postal ballots that arrive until 10 November, and Nevada until 7 November. In 2022 the House majority was not projected until 16 November. Georgia holds a run-off on 1 December if no Senate candidate wins a majority, and Louisiana’s general election falls on 12 December.
The count could also end up in court. On Sunday a federal judge threw out a Trump administration lawsuit seeking to stop Alaska certifying a defeat for Senator Sullivan, and Republicans have threatened to contest the result there.
What changes if the Democrats win?
A Democratic House or Senate could stall much of Trump’s agenda. The House must approve spending, so a Democratic majority could block or bargain over budgets, and it would gain the power to open investigations and, in theory, impeach. Hakeem Jeffries of New York would be likely to replace Mike Johnson as Speaker.
The Senate confirms the president’s cabinet members, judges and ambassadors, so a Democratic Senate would make every appointment a negotiation. If Republicans hold both chambers, Trump keeps a free hand for his last two years.
Why does it matter to India?
Because the result will move markets and could shape US policy on Iran. Indian shares and the rupee will trade the outcome on Wednesday. Trump has suggested further strikes on Iran could follow the elections, and for India, which imports most of its oil, any escalation shows up in fuel prices. A Congress that pushes back against the White House would not change America’s foreign policy overnight, but it would give Trump less room on trade, spending and war in the two years before the 2028 presidential election.
