With just days until America's midterm elections, President Donald Trump's grip on Congress is under threat. Democrats are leading national polls as Republicans fight to defend their majorities in both the House of Representatives and the Senate. For voters, the cost of living is a central concern; for Trump, losing either chamber could mean investigations and roadblocks to his agenda during his final two years in office. More than 39 million Americans have already voted early, as both parties launch their final push in an election that could reshape Washington's direction — with consequences far beyond America's borders.
