Don't forget one of the most glaring similarities. Obama has a corrupt Goebbels style MSM that is carrying his water just like Goebbels did with his control of the media. In fact the left learned their propaganda techniques from people like Goebbels. Take for instance their mind numbingly repeated catch phrases like "fair share" and "balanced approach" to name only a few.
"The great masses' receptive ability is only very limited, their
understanding is small, but their forgetfullness is great.
As a consequence of these facts, all effective propagana has
to limit itself only to a very few points and use them like slogans
until even the very last man is able to imagine what is intended
by such a word."
-Adolph Hitler, `Mein Kampf'
