It seems more like Americans rendered their opinion on Trumpism. Your dreams of a Fourth Reich will have to wait.
There are scary similarities between Trump and Hitler. Both feed off the adoration of their supporters. Donald Trump like Adolf Hitler are both
malignant narcissist, nationalist, racists, emotionally isolated and can not take responsibility for failures. Both have magnetic personalities before an audience but are described as rather dull in small social gatherings. Hitler had a distaste for most things not Germany. Trump has shown a distaste for anything non-American. The exaggerated threat to federal property and domestic order, used by the Trump administration as a pretext for introducing federal law enforcement in Portland and threats of the same in other cities certainly brings to mind some of Hitler outrageous use of power against his people. Trump's praises and respect for strong-armed despots and his hatred for losers are aspects of both their personalities.
There are certainly differences, one being Trump is much more knowable of business and economics where Hitler was totally ignorant when it came to business but unlike Trump was a student of history and politics. Trump's concern for international affairs is limited compared to Hitler. Also, Hitler used the personal adoration of his followers to strength and unify the nation where Trump uses it to divide the nation.
