Gen Z voters backed Democrats 66% to 31% in midterms, with Iran war among top issues

Gen Z voters backed Democratic House candidates by a 66% to 31% margin in the November 2026 midterms, marking the highest Democratic support among all age groups, according to a Tufts University CIRCLE analysis. The economy and jobs topped young voters' concerns, followed by healthcare and the Iran war, with 27% of 18-to-29-year-olds voting, the second-highest midterm youth turnout in 30 years. Young women favored Democrats by 70% to 59% among men, and support was strongest among Asian American, Black, and Latino youth. Youth turnout historically lags in midterms, and many young people report being never contacted by campaigns, with college students facing registration barriers due to frequent moves.
