On the one hand, we have candidates with actual, substantive positions that make clear they are not Republicans and not neoliberal Democrats–most clearly, Bernie Sanders and Elizabeth Warren–and then we have candidates who are selling their personality and life story and "feel good" blather, and not substantive agendas:  Senators Kamala Harris, Cory Booker, Kristin Gillibrand, and now Amy Klubochar.  I sure hope the substance wins, and the personalities go back to their mirrors.

UPDATE:  This is apt, from political theorist Corey Robin (Brooklyn College).  (Thanks to Dean Rowan for the pointer.)
