Sarah Palin Endorses Rand Paul For Kentucky Senate

Sarah Palin injected herself into another 2010 campaign Monday, with her endorsement of Rand Paul, son Rep. Ron Paul (R-Tex.), who is running for a U.S. Senate seat in Kentucky.

"Governor Palin is providing tremendous leadership as the Tea Party movement and constitutional conservatives strive to take our country back," Rand Paul said in a statement. "Sarah Palin is a giant in American politics. I am proud to receive her support."

Paul also acknowledged that he "has received a generous donation from Governor Palin's PAC."

Palin joins a growing list of Rand Paul endorsers, which includes Concerned Women for America, Gun Owners of America, Steve Forbes and RedState.com. Paul has also established himself as a darling of the Tea Party Movement and conservative groups such as Dick Armey's Freedom Works.

One recent poll shows Paul with a sizable lead over his Republican primary opponent, Kentucky Secretary of State Trey Grayson.
