Nope. There is no credible evidence at all that it's fake. There were a couple of internet crackpots that posted riduculous analyses trying to claim so, but those guys had no expertise and didn't know what they were talking about. Of course that was good enough for birthers, but that's about it.
Bullsh*t. I declared it fake the day after they were posted on line.
And like I said, your marxist friends at FactCheck are the only ones claiming its legitimacy, other than the faux CIC.
