U.S. Sen. Richard Lugar is keeping a smile on his face as he fights against the growing possibility his Senate career could be nearing its end.
Lugar spent Sunday touring northern Indiana and rallying supporters two days before the Indiana Republican primary. Various polls shows state Treasurer Richard Mourdock ahead of Lugar in recent polling.
Tea partyers have been working to topple Lugar in the primary following 36 years in the Senate. The winner of Tuesday's primary will face Democratic U.S. Rep. Joe Donnelly in November.
Lugar supporters sounded forlorn Sunday as they pondered what put the Indiana icon perilously close to defeat.
Miami County prosecutor Bruce Embrey says Lugar's supporters got caught off guard. Peru Mayor Jim Walker blames tea partyers who believe "compromise" is a dirty word.
