He absolutely has visible decline, compare youtube videos of him from 2016 vs 2020. Obviously, 4 years make difference at his age, but you can easily see how he struggles maintaining even simple conversations, which cannot be explained by abovementioned 4 years. I mean Sanders is of the same age as Biden and he did not decline nearly as much in 4 years, I; say barely changed. There is something wrong with the dude, and lots of people see it.
I've watched Biden live multiple times. He is not as skilled an orator as Obama was, and he indeed clearly has a speech impediment. None of that means dementia.
Either you fell for the old "youtube conspiracy hole", or you're seeing what you want to see.
I like Biden more than Bernie or Trump, and he's not wrong. His then vs now speech and debate performance is clearly not the same. He doesn't have dementia, but he's a lot slower and comes across as less intelligent than before, which is to be expected for a man his age.
It takes a lot of work and persistent energy to overcome a speech impediment. It will often return at times whenever that energy is sapped such as when tired, stressed, drunk, or yes even when aging. There is no evidence this is anything else.
