I say this as someone who opposes him utterly: Trump used to actually be a decent orator. It's... kinda sad, and kinda scary, in a way. I watched an interview he did from... sometime in the 80s, I want to say. I didn't agree with everything he said, but he seemed well composed and he made his points coherently.
Compare that to how he is nowadays and it's like it's not even the same man. Not just the raging psychopathy and egomania, but how he wanders off mid sentence and such. The cognitive decline is painfully obvious. When you figure this is a guy who had access to the best possible modern medicine his entire life, it's scary to see.
