Rand Paul, son of Congressman Ron Paul and a star of the Tea Party movement in his own right, is running a TV ad in Kentucky that features none other than Sarah Palin.
Paul is running for Senate; he polls 15 percentage points ahead of his Republican primary adversary, Secretary of State Trey Grayson. It's a top race for conservatives, second to Florida's Senate primary in the national interest it has generated. (And it's been heated. Greyson has accused Paul, in a TV ad, of being careless with U.S. national security; Paul, in his own ad, has called Greyson's spot a "lie" that "dishonors" the secretary of state.)
Palin endorsed Paul in February. The ad contains footage of Palin saying she's proud to back Paul because he supports limited government.
The Palin ad is now featured on the homepage of Paul's campaign website. Hotline OnCall's Reid Wilson reports that it has been airing since Monday, though the Paul campaign did not announce it to the media.
