Bunning Endorses Rand Paul

Sen. Jim Bunning -- who encouraged Trey Grayson to run -- has endorsed Grayson's rival for the Republican nomination, Rand Paul.

Bunning can endorse whomever he wants. But to encourage Grayson to run and then endorse his opponent is just despicable.

Plainly, Bunning is trying to get back at Senate Republican Leader Mitch McConnell, whom Bunning accused of "drying up" potential campaign donations. Bunning decided to retire after he was unable to raise the money to run for reelection.

Treacherous though it is, Bunning's endorsement is a big boost to the Paul campaign.
