The Indiana Republican Party will choose a new gubernatorial nominee, because the winner of the May 2016 Republican gubernatorial primary, Mike Pence, has withdrawn from the gubernatorial race. The Republican committee has 30 days to choose.
Indiana law does not permit candidates to run for two offices simultaneously in November. Furthermore, the deadline for candidates to withdraw is June 15. According to this story, Congressmember Susan Brooks has withdrawn from her U.S. House race, so the Republican Party will choose a replacement for her as well. Brooks hopes to obtain the party’s gubernatorial nomination, as do others. UPDATE: Indiana Congressmember Todd Rokita also withdrew from his U.S. House race, only six minutes before the deadline. Therefore the Indiana Republican Party will replace not only its gubernatorial nominee, but two of its U.S. House nominees.
