I'm not a fan of McCain/Palin and I certainly won't be voting for them. With that out of the way, I don't believe that Sarah Palin has an IQ just above "borderline retarded." When I look at her, I'm not seeing Albert Einstein in a skirt but I'm not seeing Forrest Gump either. Go to this link and do a page search for "mrtshw" (without the quotes) to see a posting claiming that the Alaska governor is not all that intelligent:

Capitol Hill Blue

The posting immediately below that one links to a probable source for this libel.

Obama's had a lot of nasty crap thrown at him too, of course. I guess personal attacks are to be expected in the waning days of a very contentious campaign, but this kind of nastiness is just plain wrong.
