The Democratic Party won control of both the House of Representatives and the Senate in a sweeping midterm victory for Donald Trump. The result was more significant than expected, including gains in states where Republican candidates had been considered strong favorites.

Historian and international security specialist Bruno Cardoso Reis told Rádio Observador that midterm losses for a sitting president are common, but described the scale of this defeat as exceptional. He pointed to Democratic victories in Texas, where the party won a Senate seat for the first time since 1988, and Kansas, where it secured a Senate seat for the first time since 1932. Democrats also won the Texas governor’s race, defeating incumbent Greg Abbott.

The new congressional balance is expected to constrain Trump’s domestic agenda. Democrats will control the House speaker’s office and congressional committees, giving them greater influence over legislation and oversight. Trump has said he would veto bills passed by a Democratic-led Congress, although overturning a presidential veto requires a supermajority in the Senate.

Democrats are expected to focus on issues including the cost of living, healthcare, tariffs and alleged corruption. Their committee control could also lead to investigations into the administration and people close to the president. Reis said impeachment proceedings were possible but unlikely to result in Trump’s removal, which would require a supermajority vote in the Senate.

The election may also affect foreign policy, though Reis cautioned against expecting a fundamental shift. The president retains broad discretion over defense and foreign affairs, but the Senate has a role in confirming senior military appointments and other nominees, while Congress can influence defense spending and legislation. Trump’s ability to veto congressional measures would remain a significant obstacle to efforts to change his policies.
