I don't see Trump as the main factor there. It's the declining material conditions coupled with the the failure of the left that's strengthening the far right. Fascism is capitalism in crisis after all.

Things have not gotten that progressive under Biden either. Many liberals are acting like delusional fasicsts warmongering against "Orc" Russians. This new Nakba is escalating under Biden. Biden and the useless democrats have refused to secure abortion rights for women. The fascist border policy under Obama has continued to escalate and is creating migrant slave child workers. At this point I see no difference. Their rhetoric means nothing if they do the same thing.
