Anybody but Biden. Kamala seems to be the expected replacement, that works. If not her, pretty much anyone else. Trump is a terrible candidate. While he has experience in show business, he’s way past his prime and pretty much any person should be able to beat him in a debate at this point.
I was actually recently thinking through people I’ve known and whether they could’ve done a better job debating Trump than Biden did. Generally any adult with a functioning mind would do better. Adults I’ve known with a HS education could’ve crushed Trump in that debate. I’m actually not sure if a homeless guy I once debated on the street regarding the meaning of pi would do better or worse than Biden, he seemed to be at about Trump’s level of sanity and if Trump won this last debate, well yeah even he’d do better than Biden. I can also think of some older teenage jocks I once knew, and while they were dumb as rocks their teenager swagger would’ve been more convincing than Biden’s rambling failed attempts to remember rote speeches.
If I try to think of who is actually about at Biden’s level, I think of myself at the age of 13, when I had a presentation in front of the class on an issue and for some reason I was struck by that early teenager nervousness, and haltingly tried to give a presentation as the class tried failingly to hide their laughter at how terribly it was going. It was probably the most embarrassing day of my life. That’s Biden’s level right there, because he sounded just like me back then giving that presentation. So any person in their late teens or older with a full grasp on sanity should be a much better candidate than Biden.
