*He was appointed chancellor but when the offices of chancellor and president were combined he received the support via plebiscite of 80% to 90% of the voters.

No.
The Anschluss was supported by 90+ percent of Austrians.
Neither of these plebiscites were anything near “fair” or “free”.
Since Hitler was heartily supported it would seem none in the plebiscite was forced to vote so “free” would fit, and as to “fair”, how many dead people just voted in the U.S. election?, but the plebiscites were for sure democratic.
Under the fairest and freest of circumstances the majority deme can pick a monster.
