Young voters swung heavily toward Democrats in Tuesday's midterm elections, with 66% of voters ages 18–29 backing Democratic House candidates compared to 31% for Republicans, according to preliminary data from Tufts University's CIRCLE project. The 35-point Democratic advantage more than doubled the 14-point edge seen in the 2024 national House exit polls, raising fresh questions about whether the GOP can build a lasting coalition among younger Americans.
Democratic support among men under 30 rose from 51% in 2024 to 59% in 2026, and among young women from 61% to 70%, according to 2024 exit polling by Edison Research and CIRCLE's updated 2026 analysis of NORC data. In the SSRS survey, young white voters favored Democrats 63%–34%, after splitting 50%–48% in 2024.
Democratic candidates also drew overwhelming support from young voters in major statewide races, according to preliminary SSRS polling. In Texas, 76% of voters under 30 supported Democratic Senate candidate James Talarico and 73% backed Democratic gubernatorial candidate Gina Hinojosa, according to CIRCLE's state analysis. In Georgia, 70% of young voters supported Democratic gubernatorial candidate Keisha Lance Bottoms. In Ohio, more than 60% favored Democratic candidates for Senate and governor. In Iowa, where young voters backed Trump in 2024, Republican Senate candidate Ashley Hinson lost ground with the group, according to AP Voter Poll data, and Democrats Josh Turek and Rob Sand won the Senate and governor's races.
"Gen Z voters are proving that they have the power not just to decide races, but to be the decisive factor in flipping both chambers of Congress," said Santiago Mayer, executive director of the Gen Z-led voter outreach organization Voters of Tomorrow. The group credited its youth outreach in Iowa with helping Democrats win three U.S. House races.
The strong Democratic showing follows warning signs visible in pre-election polls. An October Harvard Youth Poll found voters ages 18–29 who said they would definitely vote favored Democrats 63%–26%, while just 9% of young Americans said the country was headed in the right direction.
CIRCLE found that 79% of young Black voters and 71% of young Latino voters backed Democratic House candidates. However, young voters made up an estimated 11% of Tuesday's electorate, down from 12% in the 2022 midterms. That smaller share does not show whether turnout among eligible young voters rose or fell; their numbers could have grown even as a larger overall electorate reduced their share. Different polling methods between 2024 and 2026 also complicate precise comparisons.
Despite the overall trend, Republicans may not have lost the young conservatives who helped Trump win in 2024. An earlier More in Common study identified a faction of younger Trump supporters holding more hard-line views on gender roles and religion.

Analysis
Why This Matters
The youth vote is a critical swing demographic; the 2024 election saw Republicans make inroads with younger voters, especially men, fueling talk of a realignment that appears not to have materialised in 2026.
Control of Congress was at stake; if youth turnout and Democratic preference were decisive in flipping seats, the result reshapes the political landscape for the next two years.
The data suggest that any generational shift toward Republicans was short-lived, with young voters returning to their traditional Democratic leanings, a pattern that could persist in future elections.
Background
After the 2024 election, some analysts argued that the GOP was building a lasting coalition with Gen Z voters, particularly young men. The 2026 midterms provide a test of that theory, and the preliminary exit-poll data shows a strong swing back toward Democrats among nearly every demographic of young voters. The election came amid continuing voter concerns about the direction of the country, with only 9% of young Americans feeling the country was on the right track in an October Harvard Youth Poll.
Key Perspectives
Santiago Mayer, Voters of Tomorrow: Gen Z voters are proving they can be the decisive factor in flipping both chambers of Congress. His organization credited its youth outreach in Iowa with helping Democrats win three U.S. House races.
More in Common study: A faction of younger Trump supporters hold more hard-line views on gender roles and religion, suggesting the GOP may retain a base of young conservatives even as the broader youth vote swings Democratic.
What to Watch
Whether youth turnout rose or fell in absolute terms once final data is released, and whether lower share of electorate (11%) reflects a decline or a larger overall vote.
How Republican candidates and strategists adjust their messaging to younger voters in light of the 2026 results, especially among young men and white voters.
Whether the Democratic advantage among young voters holds into the 2028 presidential cycle or whether it is a one-time reaction to the Trump-era political environment.
