here’s a quick thought experiment:

having heard what comes out of trump’s mouth, seen the NYT & Holt interviews, the tweets, imagine trump discussing a policy position. in depth. foreign, domestic, i don’t care. a singular one, his choice. at length. with on topic, detailed follow ups.

coherently, with clarity and understanding.
multiple hours? an hour? 30 minutes? 15?

even just five minutes demonstrating nuanced knowledge about some issue

you can’t, can you?
