He can’t be THAT stupid.

And I mean that without sarcasm. Nobody who has amassed that kind of power in DC is that stupid. Period.

It's not a matter of stupidity, my good FRiend.

It's a matter of clarity and cognition and coherence.

I happened to be in the audience when as (cough, cough) veep Biden delivered a speech, approx 2012. I was impressed how he tended to wander and lose focus (but continued to speak) a few times. We, in the audience, were generous and polite, but I'm sure most remember the VEEP's vacuous moments.
