Could Sarah Palin really be so poorly informed that she does not know that North America is made up of Canada, the United States, and Mexico? Based on the Katie Couric interview, I could believe it. On the other hand, when I did some googling, I found sources that include Greenland, the islands of the Caribbean, and parts of Central America within North America so maybe the answer is not really so obvious.
I am frankly disgusted by the weasels in the McCain campaign. They deserve scorn if they are just trying to cover up for the failures of their candidate and themselves. They deserve even greater scorn if they really knew that Palin was that stupid and they did nothing to stop her from coming within a heartbeat of the Presidency.
