Indiana Republican state lawmakers who broke with President Donald Trump over his call to redraw the state’s congressional district lines are facing primary challengers who are backed by Trump and national conservative groups. The election Tuesday is the latest one to test the limits of Trump's influence with voters ahead of the midterm. Trump is targeting seven state senators who defied months of White House pressure by voting in December against mid-decade redistricting. Trump undertook the national campaign to redraw congressional maps to boost his party’s chances in the November midterm elections.
