Watching the Republican and Democratic conventions, with the stark visual contrast in the kinds of people on those different floors, always gets me thinking about how we vote, in part, by tribe. Those people just don’t look like my people, I can’t help thinking, and I’m sure those people think the same thing about my people. Large swaths of the country trust and identify with the convention of those who are overwhelmingly white, blond, neatly suited, perfectly coiffed, and highly shaved. Others find those faces terrifying, and trust the multicolored, untucked, multi-patterned hordes, many of whom appear never to have met a razor or a hairbrush, who will gather next week.
