Jeff, you asked "when have you EVER, in your entire life, seen a candidate persist after a stroke that plainly damaged his cognitive and sensory abilities?" I have not. However, I am quite reminded of our president.
Well, Biden did have at least one brain aneurysm surgery in the 80s. Some say, two. Not many are aware of that. Or his history of plagerism and just outright lying. That's what got him kicked the FIRST time he ran for president in 1987.
