Oh, and BTW, the Africa story was likely a hoax. Not that something like that would change any of your critical thinking (as I alluded to earlier)
The story that Governor Sarah Palin did not know that Africa is a continent appears to have been a hoax. What's more, the alleged source of the hoax, a "senior McCain advisor" named Martin Eisenstadt does not exist.
Martin Eisenstadt is the creation of a couple of film makers who also created a fake think tank for their creation to work for, the Harding Institute for Freedom and Democracy. There are also some clips of "Martin Eisenstadt" on Youtube and a blog which are also faked. The film makers claim that they created "Martin Eisenstadt" as a character for a proposed TV series.
Why did the story that Sarah Palin didn't know that Africa was a continent gain such credibility in the media? Part of the reason is that the Internet tends to magnify the old saying by Mark Twain that by the time the truth puts on its shoes, a lie can travel half way around the world. The Internet is the perfect vehicle for spreading rumor and innuendo.
