 So, Alex, I want to zero in on one thing you said here. There's nothing in his past that shows that he will go away. I've heard this from another New York Times reporter I was talking to over the weekend. And I don't think this story has been told enough publicly, at least recently. I never thought of Joe Biden as being as stubborn as a mule. I thought of him being a lot of things, of being craven and being opportunistic and ambitious. But he is headstrong, willful, almost obstinate.
