His rallies were just providing fodder for humiliation by comedians and YouTubers, he was saying weird shit, exposing his dementia signs, and mostly dragging down the approval ratings for his candidates. Did ANYONE have a bounce after Trump did their rally?

So it was decided he’d done enough damage, and cancelled the rest. Then the media started highlighting the decision, asking why - dementia, tired, damaging, a waste of time, etc? That pissed him off, so now he’s going to do those rallies anyway, no matter how much damage he leaves on his wake.
