Trump is an absolutely awful Hitler. Here's a little breakdown of Hitlers rise to power: In January of 1933 Hitler was sworn in as Chancellor, in February of 1933 the Reichstag caught fire, in March of 1933 Hitler had Parliament pass the Enabling Act which effectively gave Hitler unlimited power. By May of 1933 Hitler forced all trade unions to dissolve. By July of 1933 Hitler had essentially banned all other political parties in Germany, leaving Germany solidly in the hands of the Nazis in all areas of government. Skipping forward a year from June 30th to July 2nd of 1934 Hitler carried out the Night of the Long Knives. In August of 1934 President Hindenburg died and the office of President was abolished by Hitler. The transition to total control of Germany was now complete.
Trump has been in office since January 20th, 2017. So far he hasn't killed or imprisoned his political rivals, burned down Congress, or even gotten a law passed to give him absolute power over the government. Hitler accomplished his goals in roughly a year or year and a half. Trump is simply absolutely awful at being a dictator compared to how quickly Hitler was able to take over Germany.
