Tuesday's Republican primaries in Indiana served as a test of President Donald Trump's enduring power over the party. The president targeted state senators who had resisted his bruising campaign and rejected a mid-decade redistricting proposal to redraw the state's congressional map.
Trump sought to oust seven Republican state senators who voted against the redistricting plan, launching a campaign to unseat the dissidents. His intervention brought a national spotlight to state Senate seats that are usually the subject of quiet primaries.
The results showed a victory for the president in the deep-red state, as a majority of Indiana Republican legislators whose opponents were backed by Trump lost their primaries. Of the seven challengers endorsed by the president, at least four won.
