US midterms: House and Senate control at stake in key states

Americans are voting in midterm congressional elections, with all House seats and 35 Senate seats contested. Republican majorities in both chambers are at stake, determining President Trump's ability to maintain power in Washington. Democrats are favored to win a House majority, according to Cook Political Report, while Senate control remains a tighter race. The Economist gives Democrats a 53 percent chance of taking the Senate, with key contests in North Carolina, Michigan, and other states. Results for the House may be known by Wednesday, but Senate outcomes could take longer. Trump has filed multiple lawsuits challenging the voting process, potentially delaying results and creating a contentious election night.
