Well, part of the reason that liberals have such a hard time is that we still share a party with real corporatists, people whose basic thinking about economics traces back to Teddy Roosevelt Progressivism rather than Brandeisian or Jeffersonian democracy. We’ve got a lot of old-fashioned “small d” democrats, “small r” republicans in our party, people who believe in community based democracy and industrial liberty. That’s probably the great bulk of us, probably 90% of the members of the Democratic party believe in a Jeffersonian, Wilsonian, Brandeisian political economics. And that’s probably true for the majority of Republicans too. But then in our party you have this overlay of the old-fashioned Progressives, of people who still really believe that the main thing we should aim at is efficiency, and these people wield real power in the party. And then in the Republican Party you’ve got a leadership controlled by a weird amalgam of straight up feudalists and insane libertarians, who live entirely in a realm of theory and myth, and who also say that the main thing we should aim at is efficiency.
This may be the best explanation of the politics of school reform I've read (in an interview on monopoly).
