Indiana Poll Signals Mid-Decade Map Rewrite Could Cost Republicans at the Ballot

With Indiana Republicans preparing to meet this week to weigh a special session for redistricting, a new poll commissioned by Unite America found mid-decade redistricting widely unpopular among voters — including GOP primary voters. 

The survey found that 44% of Hoosiers oppose redrawing Indiana’s congressional map outside the regular process, while just 31% support it. After hearing balanced arguments from both sides of the debate, opposition jumps to 69% — with only 21% in support. The caucus meeting comes just days after Vice President JD Vance visited Indiana to rally support for the proposal, underscoring how deeply involved the Trump administration has become in the state’s redistricting push.

“Voters across Indiana — including a majority of Republicans — are sick of partisan games that put party over country,” said Unite America Executive Director Nick Troiano. “If lawmakers want to build trust, they’d be wise to focus on issues that directly affect Hoosiers’ everyday lives, instead of wasting taxpayer dollars to further gerrymander Indiana's Congressional districts, which are already among the least competitive in the country.”

The poll, conducted by 3D Strategic Research, reinforces concerns voiced by some Indiana Republicans that redrawing the map is unnecessary — and even potentially harmful to their electoral prospects. All Hoosiers, including an oversample of GOP primary voters, prefer the governor and legislature focus on issues that directly impact their quality of life — such as the cost of living and public safety — rather than redrawing the maps.

• Only 10% of voters agree that the governor and legislature should call a special session for redistricting.
• 28% of GOP primary voters said they would be less likely to support a candidate who supports mid-decade redistricting, compared to only 17% who are more likely.
• When given a list of 14 issues, redrawing Congressional maps ranks dead last among Republican primary voters.

The poll also found that most Indiana voters oppose a proposal to close the state’s primaries to registered party members only — also under consideration by Republican lawmakers. If enacted, roughly 2 million independents would lose the right to vote in the elections that matter most, since all nine congressional districts are effectively decided in the primaries. After hearing arguments from both sides, opposition grew from 52% to 77% — including 66% of Republican primary voters.

“Every voter should have the freedom to cast a ballot in every taxpayer-funded election. I’m not surprised Indiana voters don’t want to give up that right,” finished Troiano.

The survey was conducted October 7-9, 2025 among 500 registered voters and 450 Republican primary voters in Indiana. The full poll can be viewed here. Crosstabs are available upon request.
