Indiana's Republican Senate Primary is next Tuesday, and it's drawing national attention. For the first time in decades, Senator Richard Lugar is facing a primary challenger. The person opposing Lugar is State Treasurer Richard Mourdock, a conservative with backing from local and national Tea Party organizations. Despite the fact that Lugar has maintained a very conservative voting record since entering the Senate in 1977, Mourdock and his supporters say Lugar is out of touch with ordinary Indiana voters, and not conservative enough for many Indiana Republicans.
