Biden went up a lot more, but he was taking votes away from Steyer, Warren, Buttigieg, and Klobuchar. For now, the debate still seems the most likely cause. That’s a little unusual, since conventional wisdom says that debates don’t move public opinion much, but maybe this was an exception.
Perhaps it was more the fact that the electorate just didn't know or trust the Steyer, Buttigieg, and Klobuchar centrist crowd enough to vote for them with time running out. As a result the old tried-and-true guy you know pulls in all the people. He didn't really need an inciting incident other than the looming election. Following the debate without anything else to use to make a decision on, the choice was fait accompli.
