Young voters drove Democratic wins in key Senate and House races
Exit polls show Democrats won voters under 30 by nearly 50 points, reversing a 2024 trend where that group favored Republicans.

Democrats captured voters under the age of 30 by a margin of nearly 50 points in Tuesday’s elections, according to exit polling data. This result marks a sharp departure from the 2024 cycle, when the party lost critical ground with young people who shifted toward Donald Trump on economic concerns.
The party’s strong performance with this demographic helped secure victories in close House and Senate contests. In the Texas Senate race, Democrat James Talarico won the state by 12 percentage points overall. However, among voters aged 18 to 29, his margin expanded to 60 points.
Turnout among young Americans remained lower than that of older voters, with Gen Z comprising 11% of the total vote. Despite the lower participation rate, their votes proved decisive in races where Democrats flipped seats from Republican control.
Voters in the 18 to 29 age group cited economic issues as their top concern, with 43% selecting that category in exit polls. More than 80% of these young voters said Trump’s policies had worsened economic conditions. Similar shares expressed opposition to his tariff strategy and the decision to engage in war with Iran.
Data from CIRCLE indicates that 15% of young people who supported Trump in 2024 voted for a Democratic House candidate this year. Democrats saw particular gains among white men and Latino men, two groups that narrowly voted Republican in 2024 and voted for Democrats by double digits on Tuesday. The party also narrowed its margins with young rural voters and those without college degrees.
John Della Volpe, director of the Harvard Youth Poll, noted that the current cohort of young voters has different experiences than those who voted two or four years ago. He stated that every candidate and party must earn their votes rather than assuming loyalty. An October survey from his organization found a large enthusiasm gap, with half of young Democrats saying they definitely planned to vote, compared to just one-third of young Republicans and fewer than one-quarter of Independents.
Elizabeth Matto, director of the Center for Youth Political Participation at Rutgers University, said young adults can sway election outcomes. She emphasized that this group cares about politics and constitutes a voting bloc that both parties must pay attention to.
By the 2028 election cycle, Gen Z and millennial voters will make up more than half of the electorate. This demographic shift will influence how both major parties approach future campaigns and candidate selection.
