He's got Covid, so maybe that makes him vulnerable. And, yes, I've seen the articles about the dream of making him look strong — like Trump jumping up after getting shot — when/if he recovers from his new bout with the famous virus, e.g., "MSNBC’s Joy Reid compares ‘elderly’ Biden’s potential COVID recovery to Trump dodging an assassination attempt."
And let me add that I look at the polls every day, and I'm seeing Joe consistently outperform Kamala Harris. That must tighten Joe's grip. But you need to visualize the next 3 1/2 months, with both scenarios. Joe has difficulty campaigning. He's quite weak. Those who are polled have easily seen that. But they have not seen Kamala Harris as the presidential candidate. They have to imagine it. If Biden withdraws, and Harris becomes the candidate, and we see her speaking and fighting every day, will the polls show greater support for her? There's very little reason to think so. And that's why Joe isn't just a selfish bastard to hang on.
ADDED: I see Matthew Yglesias is writing "The VP is clearly the stronger candidate/The case for Kamala Harris, from a former hater."
