With six weeks until Election Day the math of the 2026 midterms increasingly favors Democrats, and President Trump’s standing with voters is the biggest reason why.
Midterms have long worked as a referendum on the sitting president, and Trump’s numbers are grim. His approval rating averaged 38% as of September 18, with nearly 60% disapproving. Among independents, only about 34% approve, below the 36% mark that came before Democrats’ 41 seat gain in 2018. In 2006, with George W. Bush at 37% approval, Democrats picked up 31 seats.
The generic congressional ballot tells a similar story. Democrats lead by roughly six to seven points on average, a wave sized margin, and a recent Marquette Law School poll put them ahead by 13 among likely voters.
What that could mean in seats
In the House, Democrats need a net gain of just three seats for a majority. Most forecasts expect far more. Decision Desk HQ projects Democrats winning 231 seats, Brookings’ David Barker estimates a gain of 25 to 30 seats, and a Cornell model projects about 226 Democratic seats.
The Senate is tighter. Republicans hold a 53–47 majority, so Democrats need a net gain of four. Nate Silver’s forecast now projects exactly that, a four-seat Democratic gain, and gives the party a 65% chance of winning the chamber, its highest this cycle. Decision Desk HQ projects 51 Democratic seats, with Ohio, Maine, Iowa, Texas and Alaska all rated toss-ups.
Still, a wave is not guaranteed. Republican-led redistricting across the South could blunt Democratic gains even with a strong national lead. State polling is also more mixed: Republicans lead the generic ballot in Ohio and Texas. Six weeks leaves time for the race to shift. But if Trump’s numbers hold, Republicans face a steep climb in November.
