My dad went through dementia and his decline was steady for the last 3 or 4 years of his life. Watching Biden over the last few years looks so similar to my dad's progression. But my dad also became much more stubborn and he became very defiant of my mom. She had no way to control him. The problem is that Jill is not even making an effort... she appears to be pushing him forward instead of trying to convince him to step down. That is so completely irresponsible.
