Drawing parallels to Hitler is not some new idea. People did it with Obama all the time. I was in England in 2000 and saw people on the street protesting the US. They had pictures of Clinton and Bush with the Nazi uniform and Hitler mustache.
I think " he's been good for the economy and seems racist" is probably one of the weaker connections I have seen. It probably fits Obama and Bush just as well minus the good for the economy part.
