Sarah Palin raised a few eyebrows within the John McCain campaign because she didn't realize that Africa is a continent, according to aides whispering with a shamelessly right-wing news outlet.

McCain aides told Fox News chief political correspondent Carl Cameron there was "great concern" within the campaign that Palin "lacked a degree of knowledgeability necessary to be a running mate, a vice president, and a heartbeat away from the presidency."

Yes, knowledgeability.

According to Cameron, Palin didn't know which countries are part of the North American Free Trade Agreement (NAFTA) - that would be the United States, Mexico, and Canada - and she didn't know that Africa was a continent rather than a "country just in itself".

Not that any of this is a surprise. ®
