Actually, the Germans did vote Hitler into a constitutional office. However, he then created the Reichstag fire, blamed it on the commies, and demanded unlimited executive authority to deal with the threat. The granted it for a period of one year, and the first thing he did... dissolved the German Congress..
There were 3 parties in Germany at the time of the election of Hitler, and he won with 38% of the vote... just pointing that out.
What really happened was Franz von Papen appointed Adolf Hitler Reich Chancellor of Germany. Shorly after that, deranged Communist, Martin Van de Lubb (sp) burned the Reichstag and Hitler cleverly used that to assume dictatorial powers. Shortly after that, a plebiscite was held in Germany on whether to approve Hitler’s actions and Hitler got a 95% JA vote. That was the vote after Hitler was appointed by von Papen. Foolish von Papen thought he could control Hitler, but Hitler outsmarted and out maneuvered him and everyone else.
