Since everybody else is piling on, let me add my own comment to the fray. If you were one of the people who participated in that Vanity Fair hit piece, and we find out your name, you will be a net drag on any national campaign for the rest of your professional career. Not because you helped the Left go after Governor Palin, but because you are an untrustworthy sneak who is dedicated to propping up the elitist system in DC, not fixing it. Any candidate that hires you will have to overcome the base's natural reluctance to work with a campaign that would hire someone like you. This can be done; but it's much easier to hire people with your skill set and a name for basic party loyalty.
If you are a McCain staffer who did not talk to VF, I suggest that you find some way to demonstrate that you aren't one of the people in the first paragraph. Because until we know who talked, the default assumption is going to be that you may have talked. This will not wreck your career, but it will blight it if the base has anything to say about it. On the bright side, a simple and declarative denial will do; of course, if your denial is a lie and we catch you at it, brush up on your typing skills.
