In rode the man on the white horse, whom no one really needed. And when he got there, he didn't resolve the impasse, and he didn't propose a plan. He just sat there, er, blinking. Now he's tied himself into the comic position that this deal isn't made by tonight, he won't show up at the debate, so there.
It's like a seventeen year old going to their room and slamming the door when he can't be the center of attention.
