Just a little nitpicking. Hilter was not elected. The NAZI party won, I believe, 22% of the parliament seats. Hilter was appointed Chancellor by President Hindenburg.
Correct, from where he proceeded to use intimidation and false flags to create a coup to install him as Chancellor and absolute ruler, making Hinderburg pretty much nothing but a figurehead until he passed away.
Hitler never won in any fair election. However, after he was appointed Chancellor, he never lost an election. His biggest constituency was in the north among rural Lutherans. He had the least support in the Catholic areas in the south.
