For me I think it's because the very DNA of the US is founded upon fascism and evangelical extremism (the pilgrims were extremists wanting to make a one religion state as history shows and were fully into murdering and supressing those that did not follow along). Add in the genocide of Native Americans, enslavement of Africans into a near industrial scale globalized slave trade system, the suppression of voting to only landed white males originally and tbh it's amazing we haven't gone full fascist earlier and I only think it's because there was a somewhat credible leftist threat in the early 1900s with truly militant labor taking inspiration from the Soviets as well as many leftist social movements continuing into the 80s. However as we see now the state itself has learned from these movements such as via the militarization of police, the NSA being part of the surveillance state, and how the FBI and CIA have legally and illegally involved themselves in sabotaging anything threatening the status quo.
