Seven Indiana Republican state senators lost their primary elections after voting against a redistricting plan backed by former President Donald Trump. The senators, including Greg Walker, Jim Buck, and Linda Rogers, faced Trump-endorsed challengers in Tuesday’s primaries. Walker, a 20-year veteran of the state Senate, lost to Michelle Davis, a Trump-backed challenger. Buck and Rogers also lost their races. Only one of the seven senators, Greg Goode, advanced to the general election, while another race remained too close to call.
The senators had voted against the redistricting effort in December 2025, which was designed to shift two House seats in Republicans’ favor. Trump had aggressively lobbied for the plan as part of his broader campaign to redraw district lines to boost the GOP in the midterm elections. The senators cited overwhelming opposition from their constituents as the reason for their votes against the plan.
Walker, in an interview with NBC News’s Meet the Press, said he stood by his decision. “I made the right choice,” he said. “I’ve served my district well for 20 years.” He also criticized the proposed map, saying it would not provide the desired results. “This is ridiculous, and this will backfire,” he said. Buck and Rogers similarly expressed no regrets about their votes, stating they followed the wishes of their districts.
The redistricting effort was seen as an unusual mid-decade attempt to alter congressional maps. Experts noted that Trump’s influence in Indiana politics remained strong, despite the backlash from the senators. The current congressional delegation in Indiana is split 7-2 in favor of Republicans, but Walker suggested that the breakdown could shift to 6-3 if the margins of safety in some districts were reduced.
