This is a positive sign for the Tea Party, who many pundits have written off, but the job will not be complete until Mourdock wins in November. The Indianapolis Star's Mary Beth Schnider has more on Tea Party challenger Richard Mourdock's decisive victory:
Sen. Richard Lugar’s 36-year Senate career is now history.
Lugar was defeated in today’s Republican primary election by Treasurer Richard Mourdock, ending his bid for a seventh term in the U.S. Senate.
It wasn’t even close.
With 70 percent of the vote counted, Mourdock had 60 percent to Lugar’s 40 percent.
Mourdock will face Democrat U.S. Rep. Joe Donnelly and Libertarian Andy Horning in the November election.
