House Races to Watch in the 2026 Midterm Election
Republicans hold narrow majorities in both chambers, and Democrats need just a few House gains and four Senate seats to take control.
On Tuesday, November 3, 2026, millions of Americans head to the polls for midterm elections to decide control of the U.S. House of Representatives and Senate, as well as governorships in 36 states.
This election, on track to be the most expensive in U.S. history, features $11.9 billion in total spending and record early voting with more than 57 million ballots cast as of Monday, November 2, 2026.
CBS News identifies 11 key Senate and 42 House races that will likely decide the majority, with competitive contests unfolding across Pennsylvania, North Carolina, and Iowa.
Democrats must gain a net of four seats to flip the House, where Republicans currently hold a 218-214 majority, while also overcoming a 53-47 Senate disadvantage.
The outcome will shape the final two years of President Donald Trump's administration as the 2028 presidential cycle begins, with officials preparing for potential legal challenges to results.
