Trump’s influence tested in Indiana Republican state Senate primaries

Indiana’s primary will test President Donald Trump’s enduring power over the Republican Party as he tries to dislodge state senators who refused to go along with his call to redraw the state’s congressional map.

Twenty-one Republican senators voted against redistricting in December, including eight running for reelection this year. Trump has endorsed primary challengers against seven, and the president’s allies have spent millions of dollars on races that rarely get much attention from Washington.
