The Indiana House approved a new congressional map on Friday that would give all of the state’s seats to Republicans, though it is unclear if the measure will pass the state Senate. Republicans hold supermajorities in both chambers, but some senators have already voiced opposition to the plan.
The House passed the measure 57-41, targeting the two Democrat-held districts: Rep. Frank J. Mrvan’s 1st District in the northwest and Rep. André Carson’s 7th District centered in Indianapolis. The new map would dismantle Carson’s district, splitting Marion County among four districts. Under the redrawn lines, the 7th District would shift from a seat that supported Kamala Harris by over 41 points to one that would have favored Donald Trump by 38 points. Mrvan’s district, which Trump narrowly lost in 2020, would shift to a district he would have carried by 12 points. Overall, Trump would have won every Indiana seat by double digits under the proposed map.
The Senate is expected to take up the redistricting plan when lawmakers return on Monday. Twelve House Republicans joined Democrats in opposing the measure, reflecting divisions within the party. Senate leaders had initially resisted mid-decade redistricting, citing insufficient support, but faced public pressure from Trump, who criticized GOP senators opposing the effort and signaled he would back primary challengers against them.
The redistricting debate has sparked tensions and safety concerns, including swatting incidents targeting at least 11 Republican lawmakers and a pipe bomb threat at the home of GOP state Sen. Jean Leising, who continues to oppose the plan. She emphasized that she remains focused on constituent needs rather than changing district lines.
The Indiana redistricting effort is part of a broader national trend of mid-decade map changes. Texas recently approved a GOP-favored map after a Supreme Court ruling, while California voters passed a Democratic-favored map. Other states considering redistricting include Missouri, North Carolina, Ohio, Utah, Maryland, Virginia, and Florida, with potential seat shifts for both parties depending on the state.
