I agree with the first bullet point but does not change my stance on biden. I felt both him and trump were to old but once you have a known good quantity vs a known bad I would rather stick with the good. This pretty much applies to the second bullet point. For the third did you see the debate? He handily won if you listened to what they said. Yeah its easier for trump to be energetic and fast in what he says when he does not have to care about accuracy. Biden having to actually think about what he is saying makes for some an appearance that might look bad if you focus on appearance but content wise he was miles ahead. This is something which again causes someone like me to want to go with him. I mean the appearance folks are pretty much maga anyways except for the folks who are like, other people but of course not me vote on appearance and will sink it. Now granted I would be fine with your end scenario. I was not wild about the change to kamala but once it was done I supported her like I voted for hilary. I think a lot of this thinking is all supposition about how other people feel.
