McCain campaign using Bristol?

Josh thinks so,

It was the McCain campaign that announced Palin's daughter's pregnancy. That alone might be understandable since it appears a supermarket tabloid was about to print the story. But it was the McCain campaign, entirely on its own, that dished up unsubstantiated claims about maternity tests and all sorts of other lurid nonsense that had never been seen in print anywhere. And now the McCain campaign has staged a ceremonial laying-on-of-hands on the tarmac in St. Paul in which Sen. McCain has given his official blessing to the young couple and embrace of Bristol's boyfriend Levi....

Let's be clear about what's happening here. Overwhelmingly, reporters are pressing eminently reasonable questions -- her role in troopergate, her lack of experience, her connections to the AIP, her history of earmarking and lobbyists, etc. Meanwhile, the McCain campaign is going absolutely non-stop about Palin's daughter. It is unmistakable.
