After reconsidering his first impression following a storm of disagreement from his readers, John Cassidy at The New Yorker still thinks Hillary Clinton won the Democratic debate. Clinton had the most to lose going into the debate, because her numbers were down due to the persistent media focus on the private email server "scandal". Her performance in the debate was stellar, and she came across as much more likable than in previous media appearances.
Bernie Sanders was Bernie Sanders, the same person we know (and love?) from his frequent speeches and media appearances, and few, if any of us, expected him to be other than the man we already know. He was himself, and he performed excellently in the debate.
My less than expert opinion is that neither of the two principal candidates won or lost, and both did very well. Sanders gave Clinton an enormous boost when he said:
The American people are sick and tired of hearing about your damn emails!Martin O'Malley had several good moments in the debate, and his final statement was superb. In a few words, he summed up the difference between the candidates in the GOP and the Democratic candidates. I like having him on the stage as a foil for both Sanders and Clinton.
I'm not sure why Jim Webb and Lincoln Chaffee were on the stage, but neither gained from their inclusion in the debate.
