Bloomberg's decided to give over a million dollars to McAuliffe for ad buys in the final two weeks of the race.
Add in Gabby Gifford's PAC constantly sending out mailer and McAuliffe saying he want to ban magazines, ban private sales, and limit people to one gun a month...
well, you're looking at a big, big gun grabber reaching for that brass ring.
What's interesting is that McAuliffe as a more than comfortable lead, given his war-on-women push and that Cuccinelli is a woeful candidate. One wouldn't think he'd want to let the cat out of the bag on him being a gun grabber, then again he's a DC fixer from NY so those Bloomberg bucks are appealing.
Then again, what better way for Bloomberg to puff up his ego then come long near the finish line and gloat about how he "saved' McAuliffe.
Edit: Read the comments to get an idea that it's not Cuccinelli-boostering. As it's more god-what-an-insufferable-nanny Bloomberg is.
