Leftism absolutely is a religion. They have all the hallmarks. Their god is government.
A cult is generally built around idolatry of a particular entity that isn't God. Supporting Trump isn't a cult. However, "Trumpism" does have a few members that I think can cross that line. I think I may have met one once. I don't believe there are many of these, but there are a few out there.
But to the extent that these people exist, they aren't unique to Trump. I'd wager that just about every national figure with some level of charisma has followers like this. The cult of Obama was (is) much, much larger and significant that anyone you might say was a member of the cult of Trump.
The best way to keep evil men from wielding great power is to not create great power in the first place.
