President Donald Trump's supporters swept at least five Republican senators out of office in Indiana's primary election May 5, sending a warning sign to Republicans thinking of splitting with the president ahead of the midterms.
The senators had all helped block Trump's demand that Indiana redraw congressional districts to be more Republican friendly ahead of the midterms.
State Sen. Greg Goode made it through the primary with most of the other incumbents losing in landslides. One of the races remain undecided late Tuesday evening.
The president endorsed their challengers and his allies spent millions of dollars in what are normally sleepy state legislative races. Groups supporting the president's redistricting gambit spent about $6 million against the targeted incumbents, according to AdImpact. Other national groups funded direct mailers and field operations for the challengers.
It is uncommon for political leaders to support challenges to incumbents. But Trump promised political payback and Indiana Gov. Mike Braun, a Republican, said there would be repercussions.
