Ellsworth ran unsuccessfully for U.S. Senate in 2010 and was succeeded by Republican Larry Bucshon in the same election cycle and has since become the first representative of the district to surpass six terms. Although Southern Indiana is ancestrally Democratic, the Democrats in this area are nowhere near as liberal as their counterparts in the rest of the state. Historically, it had a character similar to Yellow Dog Democrat districts in neighboring Kentucky.
Unlike most other districts in the state, which tend to give their representatives long tenures in Washington, the 8th congressional district has a reputation for frequently ousting incumbents from both parties. Since 1983, no one has held the seat or its predecessors for longer than 12 years. Voters in the district ousted six incumbents from 1966 to 1982.
