On February 19, the Indiana Election Commission voted 2-2 that Republican U.S. Senate candidate Todd Young, a sitting member of the U.S. House, should be on the Republican primary ballot. See this story. It is possible a lawsuit will be filed to reverse the decision. Challengers to Young’s petition argue that he doesn’t have enough valid signatures in the First U.S. House district. Indiana primary petitions for statewide office need 500 signatures in each U.S. House district.
