Sally Kohn: How worried are you about populism not as an economic proposition but as a phenomenon of politicians amining key institutional norms and rules to sustain free and fair elections? She asks whether we need to be less concerned about some of the developments now in our political system. Kohn: We have a kind of difference about populism and i want to locate what that difference is. The south had this very nepotistic closed off elite and periodically there would be rebellions backed by alienated voters when they could vote, she says.
