Then we have a crisis of the ruling class, which was bullied and backed into a corner by a megalomaniacal kleptocrat who stole their candy, and who has no respect for the core institutions of class rule or for the stories his class brothers and sisters tell each other about the delights of the prevailing world order.

And a crisis of the state, in which far-right ideologues, autocrats and theocrats, having captured the governing apparatus, are rapidly concentrating power in the executive while bureaucrats scramble toward either dissent and defiance or appeasement and accommodation.

In response to these crises, a highly consequential debate about the direction of the Democratic party rages among academics, pundits and politicians. Sparked by the Columbia University professor Mark Lilla in a New York Times opinion piece, this debate is most active among liberals, but ranges both rightward and leftward as well. The controversy focuses on the role of “identity politics” in Hillary Clinton’s presidential defeat. Essentially, the debate turns on whether the Democratic party and Clinton, in their embrace of racial, religious and sexual minorities, forsook working-class white people, who responded to their abandonment by casting their votes for Trump.
