I'm pretty disappointed by some of the comments here. Because Turks voted him in that makes Erdogan's autocratic rule OK? There is no free press, hundreds of thousands that have had any association with opposition groups have been jailed, the referendum vote has been widely discredited as fraudulent. Hitler was voted into office too, I guess that just ended up being the German's problem? Democracy doesn't die without…
On a side note, Hitler was not elected into office but came in second in the election for "Reichskanzler". The NSDAP came out strongest party with 33,1%. Politicians at that time thought they could tame him if he becomes part of a coalition. They guessed wrong and he assumed full power. If you play the Hitler card at least get it right.
NPD is a German right wing party that was founded 1964 and is nothing like the NSDAP that you meant.
Fun fact: NPD was not forbidden in Germany due to too much involvement of the Verfassungsschutz (German secret service for everything inside Germany) - they paid so much money to informants on the extreme right that they managed to build solid structures in large parts of the country.
