Minor nitpick: The nazis never won a majority of the vote, needing to use another party to prop them up, and were not in support of democracy. There were various steps on the way to the Nazi dictorship which all had the veneer of democracy, but were all fake. Sure the majority of the parliament voted for the Enabling Act, but they changed the voting rules, they arrested and detained opposition members, during the vote armed villiganties were in the voting hall.
The nazis didn't sieze power democratically.
