“a political philosophy, movement, or regime (such as that of the Fascisti) that exalts nation and often race above the individual and that stands for a centralized autocratic government headed by a dictatorial leader, severe economic and social regimentation, and forcible suppression of opposition”
So breaking it down:
“that exalts nation and often race above the individual” - Trump, not Biden.
“centralized autocratic government” - Trump, not Biden (or any Democrat, really, “centralized” isn’t their thing).
“severe economic and social regimentation” - I could see this one being argued “both sides”. The difference being Democrats want to use the regimentation to protect people and Republicans want to use it to oppress people.
“forcible suppression of opposition” - Definitely Trump, not Biden.
