Another parallel:
Hitler blamed all the country's woes on the Weimar Republic, his governing predescessor.
Obama is blaming all the mess we are in on Bush and the Repubs.
Yes, Hitler was certifiable. A comparison to Julius Caesar would have been a better analogy, perhaps, but either way, the rise to power of all three men is the same. It wasn't until Hitler had consolidated his power that he brought out the Final Solution and reveal his psychopathy. Obviously, Obama is not psycho, but the cult of personality and the fawning blind obedience, the ability to whip crowds into a frenzy with oratorical skills, the promising to fix all the problems that the previous administration caused - the similarities are unmistakable.
There is a taboo in this world about Hitler comparisons. You can, however, separate the evil from the government for purposes of a discussion - the Final Solution was not the only part to his Master Plan - it was just one facet - a horrible, evil, facet, but just one part.
