CNN has called Biden's response (the one where he confused Egypt and Mexico) as "poignant".
This is pretty binary at this point. Either he has the cognitive function to face trial, and a trial goes forward, or it's the 25th Amendment. You can't be "mentally incapable" of standing trial while simultaneously being capable enough to run America. I submit that the baseline mental functions necessary to face trial are much, much lower than the mental minimal baselines for being President of the United States.
I don't want to see Kamala there, even for just 10 months, but it is becoming clearer that his mental incapacity is worse than even we have been making fun of in this thread. Which, yeah, maybe it's something that shouldn't be made fun of. My mom went through mental decline like this, but then she didn't have the gall to run for President.
