Sen. Richard Lugar of Indiana was defeated in the state's Republican primary Tuesday, ending the 36-year career of a GOP elder statesman and handing the Tea Party movement its biggest upset victory so far in the 2012 elections.

Lugar was ousted by State Treasurer Richard Mourdock, whose campaign against the veteran lawmaker was backed by conservative groups including the Tea Party Express, the anti-tax Club for Growth, the National Rifle Association, the Tea Party-aligned Freedom Works, and former Republican Alaska governor Sarah Palin.
