McCain's lawyers are reportedly vetting Palin now, 4 days after he picked her

Is McCain even in charge any more? And if he is, should he be? This is just shockingly reckless. What is McCain going to do, un-nominate Palin in a few days or weeks or months if he finds out something (else) untoward about her?

Greg Sargent reports that the McCain campaign is now refusing to say whether McCain was aware that Palin's daughter was pregnant. Earlier today the McCain campaign told Reuters that McCain was in fact aware of the fact last week when he picked Palin. As Greg notes, the story is less about the daughter and more about McCain. Palin's unmarried, 17 year old daughter being pregnant (we don't know how old she and the baby's father were when they conceived the child), would be a relevant "controversy" for the vetting process to at least discover for McCain's private consideration.
