In deep-red Indiana, where the top offices are held by Republican politicians, this election cycle is set to bring a new wave of leadership from the governor’s mansion to the halls of Congress.

Voters in Indiana will head to the polls on Tuesday to participate in their primaries, which will include a six-way primary for governor and crowded races for several open congressional seats, in what has become a game of political musical chairs. The number of open races has driven a historic number of GOP contenders.
