Recent national polling has shown Democrats leading Republicans by 8–11 points on the generic congressional ballot among likely voters, marking an 11-point swing from the 2024 House popular vote and aligning with conditions for substantial midterm gains. President Trump’s job approval has fallen to record lows near 33%, with net ratings around -23, amid widespread dissatisfaction over inflation, gas prices, and the ongoing conflict in Iran. These trends have boosted Democratic prospects in forecasts for House control and narrowed or flipped several Senate races in states Trump carried in 2024. Prediction markets have responded to this post-Labor Day polling surge and the president’s unpopularity by pricing a Democratic wave—defined as majorities in both chambers—at levels consistent with the current implied probability.
