Democrats won both chambers, and Susan Collins lost her Senate seat
Democrats won a sweeping victory in the 3 November 2026 midterms, taking both the House and the Senate and reversing the voting patterns of 2024. The most striking results came in the Senate: in Maine, longtime Republican Senator Susan Collins lost to Democrat Troy Jackson. Analysts see the result as a rejection of President Trump's agenda more than a vote for specific Democratic policies, since many voters were reacting against the administration. With both chambers, Democrats gain the power to investigate, block legislation and slow nominations until at least 2029.
Congress is the main check on a president, so the shift changes what Trump can pass and gives Democrats subpoena power. It is also a signal for the 2028 race.
A party that holds the White House has lost seats in the House at most midterms since World War II.
