He achieved power because completely unelected people, the capitalists and old prussian generals, actually ran the show and the decided Fascisim would serve their interests better. Weimar Republic's "democracy" was a farce and the communist argument is that modern liberal democracies are also a farce for similar reasons. If the majority of society is organised unequally and anti-democratically then holding elections every four years isn't actually going to achieve rule for and by the consent of the governed.
