Trump-backed challengers topple GOP holdouts in Indiana, Louisiana and Georgia

Donald Trump’s spring campaign to punish Republican dissenters produced a blunt scoreboard across three states: Indiana, Louisiana and Georgia. In race after race, Trump-backed challengers knocked out officeholders who had resisted him, reinforcing the message that opposition inside the GOP now carries a primary-season price.

Indiana offered the clearest display of the pressure campaign. On May 5, five of Trump’s seven chosen candidates for the Indiana State Senate defeated incumbents who had voted against mid-decade redistricting, a plan Trump wanted to improve Republican odds in the 2026 midterm elections. Indiana lawmakers had rejected the push months earlier, and Trump answered with a flood of outside spending. Reports put pro-redistricting advertising at about $6 million, while some estimates placed total spending in the state-level fights between $8.3 million and roughly $12 million. One more race was extremely close, and one incumbent survived.

The pattern extended to Washington’s most visible holdouts. In Louisiana, Sen. Bill Cassidy finished third in the May 16 Republican Senate primary and lost his seat, clearing the way for a runoff between Trump-backed Rep. Julia Letlow and state Treasurer John Fleming. Cassidy was already a marked target: he was one of the few remaining Senate Republicans who voted to convict Trump in his second impeachment trial after the Jan. 6 attack, and he had also angered Trump on issues including the Jeffrey Epstein files and the war with Iran.

Georgia added another headline on May 19, when Secretary of State Brad Raffensperger failed to reach the runoff in the Republican gubernatorial primary. Raffensperger became a national adversary to Trump after defending Georgia’s 2020 election results against Trump’s pressure, and his exit left Trump-endorsed Lt. Gov. Burt Jones and billionaire Rick Jackson to compete for the nomination.

The purge even reached Kentucky, where Rep. Thomas Massie lost the GOP House primary to Trump-backed challenger Ed Gallrein in what reports called the most expensive House primary in history by ad spending. Massie had repeatedly clashed with Trump over federal spending, the Epstein files, the war in Iran and Trump’s signature tax legislation. Together, the races showed how thoroughly Trump’s endorsement operation can discipline the party. They also fed a growing Republican debate over whether loyalty tests strengthen the base or drain time and money from defending slim House and Senate majorities in November.
