The National Enquirer story is meant to be a leak from that upcoming Rogue book, right?  If so, it probably got picked up on the credibility of the author (who I think was the same guy who rented a house next to hers or something?), and it's possible that people in the media were aware of this tidbit before, but it was off the record/they needed the Enquirer to break it to not feel embarrassed.
Either way, I'm taking the same position as with the Christine O'Donnell kiss-and-tell piece.  She's not alleged to have done anything wrong, she's certainly not alleged to have done anything that would impact her performance as an officeholder (or even a pundit, really), and the coverage is more than a tiny bit sexist.  I don't mind people talking about it here, since it unifies the Bore's love of politics, retired cagers, and BBC.  But let's not try to justify this as a real story.

Fuck, I don't like defending Palin.
