US Elections 2026: Trump's midterm headache grows as polls show Democrats gaining ground in key races

US midterm elections: Four days before the US midterms, major national polls show Democrats leading Republicans by roughly 8-10 points on the congressional ballot, putting the House within reach while Trumps weak approval ratings and voter concern over the economy remain major headwinds for the GOP. The Senate is tighter, but recent CNN battleground polling shows Democrats ahead in several key races, giving the party a possible path to the four-seat gain needed for control.
