U.S. Senator Barack Obama (D-IL) (L) poses alongside Republican Senator Richard Lugar (R-IN) at the start of the Senate Foreign Relations Committee business meeting on Iraq resolution on Capitol Hill in Washington in this January 24, 2007 file photograph. U.S. Senator Richard Lugar, a 35-year veteran of the Senate and leading foreign policy voice, was defeated in the Indiana Republican primary by a Tea Party-backed challenger on May 8, 2012, the first Senate incumbent ousted in the 2012 election year. Lugar conceded defeat to challenger Indiana state Treasurer Richard Mourdock, who attacked the soft-spoken Senator for votes in support of Democratic President Barack Obama.
