He got the most votes in a few (three?) elections in the space of a few months. But not a majority. He didn't win the presidential election (Hindenburg won that).

But as leader of the biggest number of seats he had to be considered for chancellor. He didn't really get what we might think of as his total control until the enabling act was passed.

All the commie/ union/ socialist persecution in 1933 was not enough to get the supermajority needed in the March election for him to pass the enabling act on his own. He was still a minority chancellor. . . . but it turns out he needn't have worried because all the Centrist/Conservative Niemollers banded together and voted for the enabling act anyway.
Presumably they thought Hitler might favour them in the new post-Weimar government.

So you could argue that the dissolution of the weimar government was a product of (representative ) democracy. The reps in parliament just voted the parliament itself out of exitence for some reason. It was all part of the democratic system until that act was passed. Very few people in the country were happy with Weimar though pretty much since the wall st crash.
