US midterms: Democrats poised to challenge Trump's control of Congress

Polls opened on the US east coast Tuesday in midterm elections that could weaken Donald Trump's presidency, with Democrats poised to seize control of Congress and curb his executive powers. Democrats need only three House gains and a net four Senate seats to win both chambers, fueled by voter anger over inflation, energy costs, and the Iran conflict. A House loss would stall Trump's agenda and enable investigations, while a Senate defeat threatens his judicial appointments. All 435 House seats, 35 Senate seats, and 36 governorships are at stake, with over 57 million early votes cast. Trump, whose approval rating hovers near the low 30s, has alleged voter fraud without evidence, and his allies have filed legal challenges ahead of results.
