 OK, let's start with the obvious. Joe Biden had a very bad night on Thursday. There is no one, not Democratic lawmakers, not Biden campaign officials, not Joe Biden himself, who would tell you that he had a good night or they shouldn't tell you that. And remember, the biggest concern about the president from the moment this reelection campaign started was about his age and his ability to campaign effectively. The campaign wanted to have a debate early to shake up the race and silence those concerns.
