DON SURBER: Trump saved Indiana in 2016. “The message from voters to Republicans was clear—you have a supermajority, use it. Maybe Rove and WSJ think redistricting was trivial but Republican voters wanted it bigly. They want Congress to be flooded with Republicans. 9 is more than 7. The RINOs voted for 7. Ten years ago, the message was the same—you have a supermajority, use it.”
