Independent election monitors, including a former US President, certified the Venezuela elections as conforming to democratic standards. this would not be the case for the 1930's German elections, in which the brownshirts were out in force, threatening and beating the Nazi's opponents.
The Nazis were not democratically elected with a majority, or a plurality. The DNVP was elected with a minority. The Nazis were their junior coalition partner. A conspiracy of German business leaders swung a deal to have Hitler appointed Chancellor. Hitler than ran a non-democratic "election" in which he still only took 44%, assumed power anyways and ruled as a dictator.
