Would it be worth my while to go back and go over all the posts here on the "Palin/Africa" meme? I particularly like this one:

Tom, what clearly happened here is damage control. A few probably liquored up Republicans (yeah the Dems aren't the only ones that drink) let their guard down and spoke honestly about Palin in front of people they shouldn't. I say honestly not because we have court-confirmed transcripts or hidden video or audio tapes, but because the stories are absolutely consistent with other clearly observed behavior by Ms. Moose Gutting.

Once the story got legs and it appeared damaging to the GOP and the future of the wingnut savior in librarian glasses, a bunch of Republican clean up experts (and yes they have names) came out and denounced the stories. That proves or disproves nothing only your gullibility.
