Richard Lugar, after 36 years in the Senate, is projected to lose the Indiana Senate primary to state treasurer Richard Mourdock. The 80-year-old Lugar is the longest-serving Republican in the Senate, along with Orrin Hatch of Utah, but he faced a challenge by those in his party who felt he was not conservative enough on federal spending. Mourdock was backed by a variety of conservative groups, including the National Rifle Association. The Democratic candidate will be Rep. Joe Donnelly, but it is not clear if he can raise enough money to be truly competitive in November.
