Republicans in Indiana hope voters will help them retain three congressional seats without incumbents running, while they also aim to knock off an incumbent Democrat in the northwest part of the state.

Eric Sorensen is facing Republican Joe McGraw in the 17th Congressional District, while Rep. Nikki Budzinski is being challenged by Republican Joshua Loyd in the 13th District. Already, Democrats are leading in fundraising and have a political map that favors incumbents.
