Strokes do not change timbre. Maybe diction. But the basic differences in old Joe and new Joes are not stroke victim or dementia. And that does not explain the distinct biometric and voice differences between actor Joe, mask Joe and CG Joe.

You realize in the presidential debates that Trump told us that was not the real Joe? Why do you think he trapped him into fucking up his own alma mater? And then mispronounced his name with heavy emphasis. And was called the hologram in the basement by Michael Savage? Because he is a fake. What about the two different hairlines between the doubles that do not match the original Joe Biden? Dude got plugs in the front and the sides?

Biden has talked about having problems stuttering since he was a kid. That's not really anything new.
