Wrapup: I know I'm partisan, but McCain seemed completely out of his depth tonight. He was flitting from point to point all night without ever putting together a coherent argument, and then grabbing miscellaneous attacks from the rolodex in his head whenever some bright idea popped into his mind. His energy level was weirdly erratic, tired at times but then suddenly perking up whenever he got annoyed by something and remembered some zinger that he wanted to fire off.
McCain also interrupted a lot, and when he did he seemed clearly upset. That really didn't sound presidential.
