Overview
On December 12, 2025, Indiana's Republican-dominated state senate delivered a stunning rebuke to President Trump by rejecting a mid-decade redistricting plan aimed at flipping the state's two Democratic congressional seats to GOP control. The vote, finalized late Thursday at approximately 4 PM EST in Indianapolis, saw 21 Republican senators join all Democrats in a 28-21 defeat of the measure pushed by Trump's allies[1][2].
Key Developments
- Indiana State Senate voted 28-21 against redrawing congressional maps, with 21 Republicans siding with Democrats to block Trump's plan targeting all nine seats for GOP gain[1][2].
- Heritage Foundation's advocacy arm warned lawmakers: 'If the Indiana Senate fails to pass the map, all federal funding will be stripped from the state. Roads will not be paid. Guards bases will close. Major projects will stop.'[2]
- GOP senators reported receiving violent threats from Trump supporters prior to the 4 PM EST vote[2].
- President Trump reacted sharply, vowing to back primary challenges against dissenting senators at 6:45 PM EST via social media[1].
