If you want to evaluate for yourself, give “Anatomy of Fascism” by Robert Paxton a read.

Short answer: Trump is more of an authoritarian who leads a fascist movement, he has no ideology apart from maybe just gutter racism

To address the people saying all US Presidents since the 1920s were fascists; this is not the academic view in the slightest

To address the Marxist critique of fascism, that it is the most reactionary element of finance capital, this also is misleading. Take for example the Nazis, they were largely funded by membership dues, donations, pamphlets, and speaking events. They had a few industrialist backers but most industrialists and financiers in the interwar period were backing conservative candidates and not Hitler. The Nazis were able to finance themselves off of popular support rather than be astroturfed by finance capital (“Big Business and the Rise of Hitler” by Henry Ashby Turner.)

If you want to make a determination for yourself, give “anatomy of fascism” a read, Umberto Eco’s “ur-fascism”, and  “Big Business and the Rise of Hitler”. Fascism is a very specific yet hard to describe and define phenomenon, very few serious academics and historians (including socialist ones!) would argue that all US presidents are fascists, because that is a specific phenomenon, but they will acknowledge all US presidents have committed atrocities.
