A few facts to add here about Hitler here:
He was far from being an unknown politician in Germany when President Paul von Hindenberg appointed him Chancellor in 1933. In fact, AH, was the most well known and arguably most popular politician in Germany at that time. In point of fact, Hitler was a household name in Germany since the failed Munich Beer Hall Putsch in 1923.
Hitler’s views were well known to the German people long before he became chancellor and were spelled out in depth in his top selling autobiography Mein Kampf.
There is nothing murky about Hitler’s origins, birthplace, or parentage. His father, Alois, was born out of wedlock, and there is some debate as to who is real father was.
Comparisons between BHO and AH I think are bit over the top. Hitler did come from a remarkably similar background that produced another one of his contemporaries: Joseph Stalin. Both Stalin and Hitler had alcoholic fathers who beat them senseless. I’m sure both would have prefered their fathers had left home. Both had protective mothers who tried to shield their sons from the abuse. Both mothers encouraged their sons to enter the priesthood. Both Hitler and Stalin were wanderers and shiftless until they found their calling in totalitarian political ideologies.
As for BHO, let’s compare him to people he is more like: Saul Alinsky, Van Jones, Anita Dunn, Valery Jarrett, Rahm Emanuel, Bill Ayers, Rev. Wright, Fr Pfleger, Eric Holder, Frank Marshall Davis, Louis Farrakhan, Cass Sunstein, etc.
For the time being. I think Obama's an Enabling Act away from lighting one hell of a big powderkeg, though. Think "Health Care Reform" or Cap and Trade or Amnesty for Illegals.
