Had a few drinks with a politically savvy good friend last night who has been a solid Clinton supporter until just a month ago when he switched to being a Bernie guy. Like myself, the appeal of Bernie is that he is a "leader", meaning that he is trying to lead to a fresh place, while Clinton is merely a political operative.
Neither of us is anti-Clinton, however. We both think that Sanders is sophisticated enough to pivot at, or after the convention, but will strategically not cease to "lead" until that point.
