Trump, as well as Putin, is an elected body, this means the people voted them for be their representatives.
Hitler was elected, Mussolini was elected, Mao Zedong was elected... most fascist dictators are elected
Some of them rig the elections by murdering their opponent, throwing them in jail, banning them from being listed on the ballot, etc
Putin didn't win with 77% of the vote because people love him that much... he rigged the election
