People sometimes refer to someone as "the next Hitler"; Who was Hitler "The next of"?

by IllogicalBeans

Who was Hitler being compared to when he was coming to/in power? Is there just this long line of "[Person people think is terrible] is the next [Past person people think is terrible]"?

Please note that there was no statement of opinion in this question. I don't mean to cause trouble, I just can't ask the question without having people fill in the blanks.

Question: These days Columbus seem to have a really bad rep (SouthAmerican here: I do think of him as evil, but that's not the point now). Is this something recent? Or people in the 1800's were already having that image?
