INDIANAPOLIS (AP) — Republican Sen. Richard Lugar of Indiana has shown through a lengthy Senate career that he can broker compromises on international and domestic issues, and avoid the acrimony that often brings Washington to a halt.
It's just those qualities that may end up costing the former Rhodes Scholar and Indianapolis mayor the seat he first won in 1976.
Lugar is facing perhaps his toughest GOP challenger ever in tea party-backed state Treasurer Richard Mourdock, who hopes to end the incumbent's 36-year Capitol Hill career with a victory in Tuesday's primary.
Public polls show a close race, though internal surveys by several Republicans show Mourdock with a slight edge.
Mourdock says Lugar is not conservative enough for the right-leaning state and portrays the incumbent as nothing more than a Washington insider.
