 Those of us who follow politics for a living, we see politicians be defiant all the time, right before they drop out. You look at Ron DeSantis this spring. He was defiant for three days after his big primary loss, and then two or three days later, he was out. To have any congressional Democrats really calling for their party's nominee and their sitting president to withdraw four months from the election is quite extraordinary. It's the kind of thing that doesn't even happen once a generation.
