Washington, Nov. 5 -- Democrats won control of both the Senate and the House of Representatives on Tuesday, breaking through in Republican strongholds that had shut them out for generations as tens of millions of Americans delivered a damning verdict on President Donald Trump. Voters in the conservative states that powered Trump's return to the White House two years ago moved decisively towards the Democrats, driven by frustration over the war with Iran, worry about the cost of living and anger at the way Trump has run the country, polls suggested. In an interview with Fox News, Trump said he would work with Democrats on issues such as immigration, but threatened to veto any "insane" bills they passed. Overriding a veto requires a two-thirds majority in both chambers. Vice President JD Vance said voter frustration over the war in Iran and the US-Israel relationship doomed Republicans in the midterm elections, distancing himself from some of President Donald Trump's policies before a possible 2028 White House bid. "The reason we lost is the war. The president himself said so last night," Vance said in a lengthy X post Wednesday. Vance went further than Trump did in blaming the war for the Democrats' landslide victory. "If you'd like to argue it was worth it, that losing the Senate for the next 6 years was worth it, then do so," Vance wrote. "Argue it was a worthwhile cost to pay. Agree or disagree, that's at least honest." Speaking later in the day, Trump -- when asked about Vance's comment -- said: "it's true to an extent, because of the spike in gas prices. But if I had to do it again, I would because Iran cannot be allowed to have a nuclear weapon". The fallout from the results will be watched closely in New Delhi, because the Democrats' stated priorities, the Iran war, Trump's global tariffs and the Trump family's business dealings, all touch India. The Iran war has disrupted shipping through West Asia and killed Indian seafarers, and Trump's tariffs are the subject of India's trade negotiations with Washington. Gregory Meeks, the New York Democrat expected to chair the House Foreign Affairs Committee, has long backed the US-India partnership and has criticised the administration's handling of ties with India. A Democratic House is also expected to scrutinise Pakistan's dealings with businesses linked to Trump's family and associates. Trump's offer to work with Democrats on immigration will be followed closely by Indians, who receive most H-1B work visas and form the largest group of foreign students in the US. The result returns Washington to divided government after two years in which the Republican-controlled Congress rarely exercised its power to rein in Trump. From January, when the new Congress is seated, Democrats will be able to investigate the administration and Trump's family and allies, and to extract concessions on major legislation. Every bill the administration wants, government funding included, will need their votes, and their Senate majority will let them block Trump's nominees, including any Supreme Court justice should a vacancy arise. Chuck Schumer, the Democratic leader in the Senate, said there was "now a generational remake of the Senate map that is going to change America". "Americans voted for change, and now Democrats must deliver," he said. Texas, the largest Republican-held state, ended a Democratic drought that had lasted decades. James Talarico, a 37-year-old former schoolteacher, defeated Trump-backed state attorney general Ken Paxton to become the state's first Democratic senator since 1988....
