Donald Trump is turning his vendetta against Republican allies into a coordinated primary offensive this month. Backed challengers in Indiana, Louisiana and Kentucky aim to unseat incumbents who crossed him on redistricting, impeachment votes or election‑integrity disputes. The president’s endorsement, still the most coveted GOP signal, now serves as a weapon to punish dissenters in key red states.

In Indiana, seven state senators who helped defeat Trump’s map‑drawing plan face a flood of money from allies such as the Club for Growth, which has pledged $2 million to bankroll insurgent campaigns in the Midwest. Louisiana sees a Trump‑backed challenger targeting Sen. Bill Cassidy, the lone Republican who voted to convict the former president in his second impeachment.

Kentucky’s still most personal showdown pits Trump against libertarian Rep. Thomas Massie, who has resisted the president on a handful of votes and helped release Epstein files. Trump has labelled Massie a “loser” and “disloyal” in rallies, while GOP strategists warn the intra‑party war drains cash and attention from the broader fight for Congress. The primary battles now test Trump’s grip on the party.
