Blake Fiechter, a Trump-endorsed real estate agent, defeated incumbent Indiana State Senator Travis Holman on Tuesday with a 20-point margin, signaling President Donald Trump still holds control over the GOP.
Holman, the third-ranking Republican in the Indiana state senate and a member since 2008, had joined Democrats and other Republicans in voting against a redistricting measure favored by Trump. CNN commentators described his loss in the primary as a "significant sign" of Trump's power within the GOP.
CNN's Anchor Erin Burnett noted Trump is investing unprecedented amounts to fight Republicans he opposes.
National Affairs Correspondent Jeff Zeleny emphasized Holman's importance as the de facto leader of seven senators targeted by Trump, making his defeat particularly consequential for others facing Trump's opposition.
Holman's loss demonstrates voter responsiveness to Trump's massive advertising campaign supporting primary challengers.
