* Domestic policy Bernie Sanders: The Vermont socialist's passion shines through when he is talking about the need to break up the big banks, the threat posed by economic inequality and the necessity of campaign finance reform.

One major mistake: Sanders, again, passed on a chance to use a question about Clinton's e-mails to make a broader point about the sort of choice facing Democratic voters.
