The behavior hasn’t substantially changed, but the narrative is shifting. Trump took office on the back of a wave of sardonic, nihilistic memes. He was constantly excused for being bigoted and unintelligible because his dork enlightenment cronies could cynically spin everything as nine dimensional water backgammon. The fact they weren’t making sense was a plus, not a minus.
Biden dropping out and team Kamala stepping up so hard so fast on the meme front has completely taken the right by surprise. They weren’t mobilized to defend against this. So now they’re on the back foot, the memes from the mainstream left are sharper and meaner than Trumpworld has ever had to deal with before, and the messaging is laser focused.
Spouting nonsense only works if it looks like you’re winning by doing so. Don just keeps showing how old, tired, and weak he really is, so the cracks are forming. Just think of all the political capital he’s spent trying to make diapers cool, and then he makes a VP pick who Snopes has confirmed literally fucked a couch on live video.
