Democrats Favored to Win U.S. Midterm Elections

The Democratic Party is positioned as the favorite to gain control of both the House of Representatives and the Senate in the U.S. midterm elections scheduled for November 3. Forecast models from Nate Silver indicate a 95% probability of a Democratic victory in the House and a 75% chance in the Senate, supported by a 9.5-point lead on the generic ballot.

Republican vulnerabilities center on voter dissatisfaction with inflation, the economy, and trade, alongside a net approval rating for President Donald Trump that has fallen to -23.3. Critics point to perceived corruption and misrule within the administration, specifically citing the actions of JD Vance and Stephen Miller. Further liabilities include the appointment of Pete Hegseth as Secretary of Defense, the alienation of NATO allies, and an increase in national debt resulting from tax cuts for the wealthy.

Supporters of the administration contest the narrative of national decline, citing the lowest poverty rate in history and a 9.7% decrease in violent crime during 2025. They highlight the enactment of the Laken Riley Act, the permanent extension of 2017 tax cuts, and the deployment of the Golden Dome missile defense system as primary achievements. Analysts suggest that rising petrol prices and continued disruption from the Iran war could further exacerbate Republican losses.
