 My guess is that if they try to replace Joe Biden, they have no choice but Kamala Harris, which is why they haven't called on the 25th Amendment. They haven't been very vocal about who to replace Joe Biden with because they want to replace him. But the fact they're not mentioning Kamala Harris at all shows they don't want her, but they don't know how to say it. They can absolutely replace Joe Biden. I explained that in the last segment.
