Cults 101: Checklist of Cult Characteristics
3)Mind-altering practices (such as meditation, chanting, speaking in tongues, denunciation sessions, and debilitating work routines) are used in excess and serve to suppress doubts about the group and its leader(s).
There's "MAGA" and "Lock her up," but actually it's a quality of all political rallies to use mantras for the purpose of shutting down individual thought, so unless you want to call all political rallies cults, then I'm going to have to go with...no.
4)The leadership dictates, sometimes in great detail, how members should think, act, and feel (for example, members must get permission to date, change jobs, marry or leaders prescribe what types of clothes to wear, where to live, whether or not to have children, how to discipline children, and so forth).
Nope. Trump spent a large amount of time doing marketing studies to learn what his base wanted to hear and then echoed it back to them in a purer, undiluted form. I don't think that really qualifies as dictating how members should think.
5)The group is elitist, claiming a special, exalted status for itself, its leader(s) and members.
This is vague, especially seeing as Trump and his followers don't adhere to a set of goals that are clearly laid out. Those goals can be inferred, to be sure. A platform that is consistently anti-immigrant, consistently hostile to minorities and demeaning to not Christians would certainly suggest that the "exalted status" is white Christianity, but that's more of an Ultranationalist or fascist label, which is a political categorization instead of a cult label, so...no.
10) Subservience to the leader or group requires members to cut ties with family and friends, and radically alter the personal goals and activities they had before joining the group.
While this has been the result, it is not a rule to sever ties with one's family and friends in order to be a trump follower, so...no.
11) The group is preoccupied with bringing in new members.
While trump followers are certainly happy to accept new members, they have not shown themselves to be a "proselytizing" group. A group that's eager to attract new members wouldn't be so energetic about alienating others, so...no.
So I count 7 out of 14. Is that enough to qualify as a cult? The world of MAGA certainly has numerous cult-like qualities, but I think you'd need at least a majority of factors to qualify.
