Democratic candidates made up significant ground among key demographic groups in the 2026 midterms, according to The AP Voter Poll, reversing many of the gains President Donald Trump made with the traditional Democratic coalition in the 2024 presidential election.

The AP Voter Poll, a sweeping survey of more than 100,000 voters in all 50 states, showed that young voters swung sharply left.

Democratic candidates' performance among voters under 30 this year far exceeded the support this group gave Vice President Kamala Harris in the 2024 AP VoteCast survey.
