Can you imagine how Joe would feel in that situation? It's clear why he won't take a cognitive test: He fears failing it. I love Joe, but that doesn't cut it.

What we’ve already learned from the cognitive test Biden won’t take.

...And Biden’s answer to whether he grasped how badly (the debate) was going in real time — well, that could have been typical Biden rambling, something that those of us who have covered him have witnessed for years, or it could have been more.

Biden’s response, in its entirety: “The whole way I prepared, nobody’s fault, mine. Nobody’s fault but mine. I, uh — I prepared what I usually would do, sitting down as I did come back with foreign leaders or National Security Council for explicit detail. And I realized — about partway through that, you know, all — I get quoted, the New York Times had me down at 10 points before the debate, nine now, or whatever the hell it is. The fact of the matter is, what I looked at is that he also lied 28 times. I couldn’t — I mean, the way the debate ran, not — my fault, no one else’s fault, no one else’s fault.”

Excuse me, what?
