Mitch McConnell endorses Trey Grayson

The minority leader puts skin in the game in his home state, two weeks before the polls open in the primary for U.S. Senate. It's a position that reminds me of the one Democrats were in when it was clear that Martha Coakley was blowing the special election for Massachusetts's open U.S. Senate seat. Whether or not President Obama campaigned for Coakley, the result there was destined to be spun as a referendum on his legacy. And whether or not McConnell endorsed Trey Grayson, the Kentucky secretary of state who's seen his rising star blotted out by the incredibly successful campaign of Rand Paul, the result there is going to be covered as a test of his political power.

Unsurprisingly for an endorsement ad, there's no knock on Rand Paul -- McConnell simply explains to GOP primary voters that these "are critical times" and he's been spurred to back Grayson. How much does he want a Grayson win? I'd point you to James Dobson's mysterious comment about "GOP leaders" pushing for Grayson, and let you draw your conclusions.
