INDIANAPOLIS — President Donald Trump’s effort to force mid-decade redistricting suffered a major setback Friday, after Indiana’s GOP state Senate leader declared the chamber will not convene in December to redraw maps.

“Over the last several months, Senate Republicans have given very serious and thoughtful consideration to the concept of redrawing our state’s congressional maps,” Senate President Pro Tempore Rodric Bray said in a statement, after conducting a private test vote on Friday afternoon with his caucus. “Today, I’m announcing there are not enough votes to move that idea forward, and the Senate will not reconvene in December.”

It’s a massive blow to the White House’s efforts to shore up a Republican House majority next year via redistricting, and comes from a state Trump easily won last November. It marks the fourth state where efforts have stalled despite pressure from Trump and his political team.
