Former Alaska Gov. Sarah Palin (R) endorsed Indiana state Treasurer Richard Mourdock (R) over Sen. Dick Lugar (R-Ind.) in their primary contest, she announced Friday afternoon.
Palin becomes the latest Tea Party standard-bearer to endorse Mourdock: Herman Cain, radio host Mark Levin and RedState's Erick Erickson also support him, as do the Tea Party-affiliated groups FreedomWorks and the Club for Growth, both of whom have spent heavily to help him win. Other conservative groups backing Mourdock include the National Rifle Association, the Family Research Council and the American Conservative Union.
Lugar has the support of Indiana Gov. Mitch Daniels (R) as well as the pro-business U.S. Chamber of Commerce. The two are neck-and-neck in their contest, according to recent polls, with the primary rapidly approaching on May 8.
