Sanders was dynamic and forceful, per usual. I guess the question is, did he need to broaden his appeal? He's leading the polls in New Hampshire, but Buttigieg seems to be catching up. It's hard to say whether this debate will move things, but there's a danger for Sanders that his narrow appeal will catch up to him if another candidate can quickly consolidate more support. That person hasn't been Biden in Iowa or New Hampshire so far, but it could be Buttigieg. It's possible Sanders could pull in supporters from Warren with his performance tonight, but I don't think Warren had a poor night. So I don't know if Sanders did anything special to boost his standing in a way that will help him long term. But he might win New Hampshire anyway.
