Overview
- Gallup’s 2025 data show 45% of U.S. adults identify as independents, with Democrats and Republicans each at 27%.
- Among independents, 20% lean Democratic, 15% lean Republican, and 10% do not lean, yielding a 47% Democratic to 42% Republican split overall.
- The results end a three-year Republican edge in party affiliation and resemble the alignment seen during Trump’s first term.
- Younger voters drive the trend, with 56% of Gen Z and a majority of millennials identifying as independents, compared with lower rates in older cohorts.
- Independents skew moderate at 47% while Democrats and Republicans are more polarized, and the findings are based on 13,454 interviews with a ±1 percentage-point margin of error.
