I think most of his supporters seem to fall into 4 categories -
-Those who are conspiracists and have been preyed upon by mis/disinformation pushing/Qanon/anti-vax type opportunist grifters and con-artists like Trump.(The likes who listen to the likes of that ghoul Robert F Kennedy Jr)
-Those who are grifters like Trump and are riding along on his coattails pushing his content, basically audience building, trying to maintain publicity or stay relevant in order to make themselves money.(ie the likes of Musk, Loomer, Truss etc)
-Those who are scared of him and his cult and who are frightened about what going against him will do to their personal wealth and safety (This group contains the vast majority Republican politicians and activists)
- the largest group, sadly, are just completely thick as pigshit. Look at videos of those being interviewed at his rallies and it’s very apparent they just aren’t very well informed or knowledgable about anything at all. Some will be genuinely racist knuckle dragging numpties.
Unfortunately, plenty of decent people who feel disenfranchised and forgotten about, and who just aren’t generally very clued up or intelligent also fall into the first and last group. (See also Reform)
It’s depressing, because how do you get those decent people who’ve been caught up in it all to see the reality of their situation, and that they’ve been completely mugged? As
@ThatFragranceGuy said, some just don’t want to admit it, even to themselves.
