Led by conservative icon Richard Viguerie, who heads the Web site ConservativeHQ.com, a group of three dozen high-profile DeMint backers, say they will respond to the senator’s detractors “in word and deed.”

“Conservatives will not only challenge and beat more Republican senators in Republican primaries, but conservatives will stop funding and volunteering for the NRSC and the RNC,” Viguerie wrote in a letter addressed to Senate Minority Leader Mitch McConnell, National Republican Senatorial Committee Chairman John Cornyn, Republican National Committee Chairman Michael Steele. “Instead, conservatives will send their money to, and volunteer for, Senator DeMint’s Senate Conservative Fund and the candidates Senator DeMint supports.”

And Viguerie and his counterparts didn’t stop there:

“It would be our goal for the Senate Conservatives Fund to raise more money than the NRSC,” the letter continues.
