This thread clearly supports Godwins Law: http://en.wikipedia.org/wiki/Godwin's_law
"As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1." [ 3 ] [ 2 ] In other words, Godwin put forth the sarcastic observation that, given enough time, all online discussions—regardless of topic or scope—inevitably end up being about Hitler and the Nazis.
I really don't see how you can compare any modern US president to Hitler.
