Only once in 80 years has the US presidential party won both houses in the midterm elections. The Republican Party, when George W. Bush was the US president, was the only presidential party since 1946 to win seats in both houses of Congress in the midterm elections, and gained eight seats in the House of Representatives in 2002. In 19 out of 21 elections held between 1946-2026, the Presidents' Party lost seats in the House of Representatives. It should be noted that Republicans lost seats in both chambers in 2026.
