Hillary's fighting the same fight we're gonna be fighting in a general, it looks like, and she's losing using much the same tactics.
She's more substantive than Obama, but it doesn't matter most of the time. She outperformed him in multiple parts of this debate, but he parried with a smart line and the audience was laughing with him, at her.
He came off cool. She came off strident. Same ol' story. If Democrats are listening, they might concede she offered more, but many of them will just see that Obama made them laugh more often. Likeability's a ...witch, as they say.
