That's simply ridiculous. Cults are largely based on an unswerving devotion to a personality and ideology, Maga has Trump and everything they say is always carefully phrased to pay homage to the leader, never condemning a single thing he says or does.
Your cult has it all, devotion to a person who can do no wrong, little catch phrases like "make America great again" a long list of enemies that includes: non-whites, foreigners, gays, trannies, immigrants (legal and illegal), science, democracy, Palestinians, black south Africans and the list goes on and on and on.
Without trump your entire cult would fragment, crumble and blow away in the breeze.
Democrats are much more diverse, some loved Biden and many did not, some advocate for trans men to use female toilets and many did not.
