Defeat complicates the picture for Republicans across the US as they seek to redraw districts in an increasingly messy battle

The Indiana legislature’s rejection of a new map that would have added two Republican seats in Congress marked one of the biggest political defeats for Donald Trump so far in his second term and significantly damaged the Republican effort to reconfigure congressional districts ahead of next year’s midterm elections.

The defeat showed that Trump’s political might is not unlimited. For months, the president waged an aggressive effort to twist the arms of Indiana lawmakers into supporting a new congressional map, sending JD Vance to meet in person with lawmakers. Trump allies also set up outside groups to pressure state lawmakers.

Heritage Action, the political arm of the Heritage Foundation, which has close ties to the Trump administration, issued a dramatic threat this week ahead of the vote: if the new map wasn’t passed, Indiana would lose federal funding. “Roads will not be paved. Guard bases will close. Major projects will stop. These are the stakes and every NO vote will be to blame,” the group posted on X. The state’s Republican lieutenant governor said in a since-deleted X post that Trump administration officials made the same threat.
