Sen. Richard Lugar - the longest-serving senator in Indiana history - has lost his Republican Senate primary on Tuesday to state Treasurer Richard Mourdock.
The 60-year-old Mourdock, who told the New York Times it is "time for confrontation" as opposed to collegiality, also criticized Lugar for supporting the financial bailout, President Obama's Supreme Court nominees and raising the debt limit. His message was amplified by the Tea Party-aligned FreedomWorks, which held "activist training" sessions and made phone calls on Mourdock's behalf, and the super PAC Club for Growth, which spent more than $1.4 million on the race. (Lugar's campaign, which had spent $6.7 million on the race as of April, did significantly outspend Mourdock's, which had spent $2 million as of April.)
Even the Democrat candidate for the Senate seat, Joe Donnelly, may be more conservative than Lugar.
