Midterm elections could reshape Congress and curb President Trump's agenda

The 3 November midterm elections put every House seat and roughly a third of Senate seats up for grabs, testing President Donald Trump's standing midway through his term. Republicans currently hold a narrow majority in the House and a six-seat edge in the Senate, but Democrats require four additional seats in each chamber to claim control. Competitive Senate races include open seats in Michigan, a Democratic lead in Georgia, and contests in Maine, Ohio and Texas, where Republican Attorney General Ken Paxton faces Democrat James Talarico.

In the House, vulnerable districts span New York, Texas and Iowa, while redistricting has limited the number of truly competitive races. Governorships and state legislatures in 39 jurisdictions will shape local policies on taxes, abortion, education and election administration. Voter-rights disputes, immigration-enforcement data use and concerns over election integrity add further complexity to the stakes of the vote.
