On Wednesday, former Alaska Governor Sarah Palin endorsed conservative Tennessee state representative Joe Carr in his primary bid to oust incumbent Sen. Lamar Alexander (R-TN).

Carr has been hammering Alexander before the August 7th primary for voting for the Senate’s Gang of Eight comprehensive amnesty bill even after he was warned by law enforcement officials that it would exacerbate the border crisis. Even Sen. Thad Cochran (R-MS) voted against the final bill.

Palin thanked Alexander for his service and then promptly said it is time for new leaders who will have the guts to tell the Obama administration, “no mas.”

“Unfortunately, advocating and voting for amnesty, cash for clunkers, bailouts, raising the debt ceiling, and many controversial Obama administration nominees has marred the incumbent’s record,” Palin wrote on her Facebook page. “It’s time for a change.”

Palin’s announcement comes a day after conservative talk radio host Laura Ingraham, who powered Dave Brat to a shocking upset win over House Majority Leader Eric Cantor (R-VA) last month, campaigned for Brat in Tennessee on Tuesday evening.

“I am here, my friends, to help you retire the political equivalent of your old plaid sweater,” she said at the rally, as Breitbart News reported.

Palin said Carr, “a citizen legislator who brings his small business experience to bear in the Tennessee General Assembly,” is “the new voice Tennessee needs in the U.S. Senate!”

“He’s stood up to those in his own party, fighting to enact some of the toughest illegal immigration legislation in the country and working to make Tennessee the 4th most business friendly state in the nation,” she added. “Joe knows that government is most often the problem, not the solution, and he will work to reduce the size of our federal bureaucracy and always use the Constitution as his guide.”

Palin also said it was disappointing and “pretty unbelievable” that Alexander has refused to debate Carr because “the good people of Tennessee deserve to hear from both these candidates to know who will be on their side and who will choose the Washington status quo.”

“The conservative grassroots patriots in Tennessee have clearly spoken. When I visited there earlier this month, I was impressed by all the energy and momentum behind Joe Carr,” she said. “Please join me in supporting him as the Volunteer State’s next Senator!”

Former South Carolina Senator and Heritage Foundation President Jim DeMint has said that Palin’s endorsement is the most important in a GOP primary.
