Both of them were clearly demented. Trump just making shit up and Biden interrupting him to mumble incoherently, ending in “We Beat Medicaid!”

Nah he was just quiet senile instead of loud senile. I’ve had patients that are rather agreeable despite low cognitive function. They don’t wind up in the hospital as much and get discharged quicker because the agreeableness means they can accept home caregivers more safely, but they very much still need assistance with decision making. He wasn’t more coherent per se, just more able to cooperate with his handlers. Ignoring morality (a distressingly common occurrence throughout the history of humanity) is it preferable to have a leader who accepts control of the oligarchs more placidly or more chaotically? I don’t speak to my parents anymore for a variety of reasons (including politics) but one tiny spark of something they did get right was that trump is slightly harder to keep under control, and is accelerating the destruction of democracy as we know it, for better or (more likely) for worse.
