The Midwestern state of Indiana has dealt a setback to United States President Donald Trump’s redistricting push ahead of the pivotal 2026 midterm elections, voting down legislation to redraw its congressional map.
Late on Thursday afternoon, Indiana’s state Senate voted 31 to 19 to reject the proposed congressional districts, despite a strong Republican majority in the chamber.

Of the state Senate’s 50 seats, 39 are held by Republicans, and the state has voted consistently Republican in every presidential race since 1968, save for a single flip for Democrat Barack Obama in 2008.
The vote is likely to reinforce the sentiment that the Republican Party is fracturing under Trump’s leadership, as his poll numbers slump during the first year of his second term.
Trump was confronted with the results of the Indiana vote at an Oval Office signing ceremony shortly after it happened.
“Just a few moments ago, the Senate there rejected the congressional map to redistrict in that state,” one reporter said. “What’s your reaction?”
Trump responded by touting his successes in pushing other Republican-led states.
“ We won every other state. That’s the only state,” the president said, before referencing his three presidential bids. “It’s funny because I won Indiana all three times by a landslide, and I wasn’t working on it very hard.”
Trump then proceeded to denounce the Indiana Senate president, Rodric Bray, and threatened to support a primary challenge against the Indiana leader.
“He’ll probably lose his next primary, whenever that is. I hope he does,” Trump said.
“It’s, I think, in two years, but I’m sure he’ll go down. He’ll go down. I’ll certainly support anybody that wants to go against it.”
Fractures in the caucus
Currently, Indiana sends nine Congress members to the US House of Representatives, one for each of its nine districts. Two of those seats are currently occupied by Democrats.
Republican leaders in the state, however, had proposed a new map of congressional districts that sought to disempower Democratic voters in the state, clearing the way for conservative candidates to claim all nine seats in next year’s midterm races.
The proposed map was part of a nationwide effort by the Trump administration to defend Republican control in the US Congress.
Already, the partisan map had passed the lower chamber of Indiana’s legislature. On December 5, Indiana’s House of Representatives voted 57 to 41 to send House Bill 1032 to the state Senate.
The bill had the backing of Indiana’s Republican Governor Mike Braun, who encouraged the state senators to emulate their colleagues in the lower chamber.
But even before the bill arrived in the state Senate, there were cracks in the Republican caucus. Twelve Republicans in the state House broke ranks to vote against the map.
And certain Republican state Senators likewise expressed reticence.
Some Republicans, like Indiana state Senator Greg Walker, had a history of opposing redistricting efforts. He was quoted in the Indiana Capital Chronicle as saying, “I cannot, myself, support the bill for which there must be a legal injunction in order for it to be found constitutional.”
Partisan redistricting has long been a controversial practice in US politics, with opponents calling the practice undemocratic and discriminatory.
Critics also pointed out that the Indiana proposal would force some voters in urban centres like Indianapolis to commute more than 200 kilometres (124 miles) for in-person voting.
Walker joined a total of 21 Republican state Senators, including Bray, in voting against the redistricting bill on Thursday.
A nationwide campaign
But the Trump administration had invested significant time and effort into swaying the vote.
In October, Vice President JD Vance travelled to the Hoosier State to try to convince wary Republicans. US House Speaker Mike Johnson reportedly made personal phone calls to state leaders. And a day before the critical state Senate vote, Trump took to social media with a mixture of cajoling and pressure.
“I love the State of Indiana, and have won it, including Primaries, six times, all by MASSIVE Majorities,” Trump began in a winding, 414-word post.
“Importantly, it now has a chance to make a difference in Washington, D.C., in regard to the number of House seats we have that are necessary to hold the Majority against the Radical Left Democrats. Every other State has done Redistricting, willingly, openly, and easily.”
Currently, the US House of Representatives holds a narrow 220-member Republican majority, out of a total of 435 seats.
All of those seats, however, will be up for grabs in the 2026 midterm elections, and Democrats are hoping to flip the chamber to their control.
Starting in June, reports began to emerge that Trump was petitioning the state legislature in the right-wing stronghold of Texas to redistrict, in an effort to help conservative candidates sweep up five extra congressional seats.
Texas Republicans complied, and in August, the state legislature embraced a new redistricted map, overcoming a walkout from state Democrats.
Republicans in other states, including Missouri and North Carolina, have followed suit, passing new maps that seek to increase right-wing gains in the midterm races.
But Democrats have fired back. In November, California voters passed a referendum to suspend their independent districting commission and adopt a Democrat-leaning map created by state lawmakers.
Indiana, however, appeared poised to buck the redistricting trend. In Wednesday’s lengthy post, Trump warned that the state could put Republican power “at risk” if it failed to pass a new map.
He also called Bray and other Republican splinter votes “SUCKERS” for the Democrats.
“Rod Bray and his friends won’t be in Politics for long, and I will do everything within my power to make sure that they will not hurt the Republican Party, and our Country, again,” Trump wrote.
“One of my favorite States, Indiana, will be the only State in the Union to turn the Republican Party down!”
In the wake of Thursday’s defeat, Trump and his allies doubled down on their threats to remove the 21 Republican state senators who voted against the bill from office.
“I am very disappointed that a small group of misguided State Senators have partnered with Democrats to reject this opportunity,” Governor Braun wrote on social media, calling it a decision to “reject the leadership of President Trump”.
“Ultimately, decisions like this carry political consequences. I will be working with the President to challenge these people who do not represent the best interests of Hoosiers.”
