Should the Weimar Republic have banned Adolf Hitler from becoming Chancellor in 1933?

[Middle-aged Europe]

Given that the Nazis actually had lost votes in the November 1932 election as compared to the July 1932 election, and given that even with a massive curtailing of civil liberties and widespread voter intimidation they still hadn't been able to win a majority of their own in the March 1933 election, there's this old argument that had the Weimar system managed to hang only a little while longer the Nazi movement would have eventually collapsed.

Because, as other posters have noted, Hitler was a foreigner and a convicted felon who looked funny and talked in a funny way about weird stuff. Even the ones who were eventually responsible for appointing him Chancellor didn't take him serious as a person or politician.

Unfortunately, the timing was a bit bad. And as a result, about 40 million people died.
