Heather in a comment on a blog post by Jennifer Rubin said:
If those staffers are right and Palin was this bad, what does the vetting and selection of Palin say about McCain? Nothing good. If these McCain staffers are this vindictive and mean to a women they were support to help, What does it say about the McCain? Nothing good. I say this as a McCain voter, I’m glad Obama won.
In the comment before Heather's someone repeated a rumor that ex-Romney people were behind the smears of Palin. That's the first thing I've read that makes sense, although it wouldn't have to be Romney people; anyone with a dog (other than Palin) in the 2012 race might be motivated to bring the pretty pit bull down.
Which of course is why the Republican Party is in the mess that it's in; the establishment had gotten so comfy that it lost sight of some minor issues like doing what's best for the country first.
The creeps doing the back stabbing better have something to fall back on. First guess: most will take media jobs. "And here's our pet Republican, who will now parrot our party line."
Losers.
