Lugar, Indiana's long-time senator, heads into GOP primary as underdog "This is another exhilarating opportunity," Richard Lugar told reporters as the six-term Republican senator hunted votes Monday afternoon at the Wesley Manor retirement community in Frankfort, Ind. Lugar does not dispute poll number that show him trailing in Tuesday's Republican primary to state treasurer Richard Mourdock. For many Hoosiers, Lugar has been their senator for most, if not all, of their lives. But Lugar faces the very real possibility of defeat. Later Monday afternoon, Mourdock held a brief campaign stop at a church in West Lafayette. "Mr. Lugar is my opponent," said Mourdock, "not my enemy." Mourdock is confident victory is within his campaign's grasp. "I think people are going to be surprised how many counties we win," he said. The late-breaking front-runner also described a primary effort in which 3,000 volunteers will spend primary day camped at 1,300 key Republican precincts, trying to pick up last-minute votes as people enter those polling places. "The winds of change are blowing," said Mourdock.
