June 2026 Nationwide Survey: Americans Support Open Primaries

A survey of 1,141 registered voters finds broad support for open primaries, and structural barriers keeping voters out

A national survey conducted by the Independent Center asked 1,141 registered voters about their familiarity with, and attitudes toward, open primary elections. Key findings include:

  • 72.5% of respondents said they support a system where all candidates appear on one primary ballot and any registered voter can participate, regardless of party. Only 13.5% opposed the idea.
  • Among those who did not participate in a recent primary, 28.3% said they were registered with a different party than the primary being held, and 16% said their state's primary was closed to unaffiliated voters. That means nearly 44% of nonparticipants were effectively excluded by the rules.
  • 50.8% of respondents said open primaries would make them more likely to vote in primaries.
  • 52.3% said they would vote for the candidate from any party who best represents their views, rather than defaulting to a candidate from their registered party.
  • Asked why open primary reform hasn't spread more widely, the most common answer, cited by 23.8%, was that the two major parties actively block reform to protect their power.
