Kevin Williamson, who is a jerk, gets this one right.

The Democratic party is an odd apparatus in which most of the power is held by sanctimonious little old liberal white ladies with graduate degrees and very high incomes — Hillary Rodham Clinton, Elizabeth Warren, Randi Weingarten — while the manpower, the vote-power, and the money-power (often in the form of union dues) comes from a disproportionately young and non-white base made up of people who, if they are doing well, might earn one-tenth of the half-million dollars a year Weingarten was paid as the boss of the teachers’ union. They are more likely to be cutting the grass in front of Elizabeth Warren’s multi-million-dollar mansion than moving into one of their own.
