This must be a pretty big cult if Trump is even or leading in the polls.
Well yeah, it is. I mean, he won in 2016. Not just because of his cult - it's big, but not big enough to win an election on its own. He benefitted from quite a sizeable "anyone by Hillary" vote too.
He lost in 2020 because there was a more palatable opponent.
Unfortunately that opponent is now considered unfit for office. I mean, I don't think Trump is fit for office either, in a different way. As always, The Simpsons showed us the way...
