The Lexington Herald-Leader reports this afternoon that Rand Paul, son of Rep. Ron Paul (R-Texas), will officially launch his campaign for the U.S. Senate on the Glenn Beck show tomorrow.

Paul ... said recently that he may announce his candidacy on the show to draw a larger audience. Doing so could be an opportunity to raise campaign funds from across the nation, much as his father did last year as a contender in the presidential race.

Secretary of State Trey Grayson (R) is the establishment favorite on the Republican side in the race to succeed Jim Bunning (R), who announced his reluctant retirement last week.
