The hyper-democratizing of political processes likewise has had much to do with the rise of militant factions (Tea Party, Resistance) that are driving politicians of both left and right ever further toward the fringes, where they recoil from compromise on any high-profile issue, for fear of being "primaried" by more extreme forces.
What pragmatism and moderation in politics lack today is passion — a zeal to counterbalance the fevers of ideological extremisms. Historically, that needed passion came from political insiders' cynical hunger for power and its spoils — but only because they had tools with which to control factions, choose candidates and hold complex coalitions of interests together in order to win whenever they could and cut deals when they couldn't.
This story of how idealistic, purifying reforms may have deformed our politics clashes with nearly all the romantic prejudices of our age. Yet here and there it's being told across the political spectrum — for example, by Joseph Postell in "The Rise and Fall of Political Parties in America," a paper for the Heritage Foundation last fall, and by Jonathan Rauch of Brookings in, among other places, his 2015 e-book, "Political Realism: How Hacks, Machines, Big Money, and Back-Room Deals Can Strengthen American Democracy."
It's a story that helps explain how so many of our political disputes have become as immune to compromise as religious dogmas, because every "difference of opinion" is now a "difference of principle" — and concessions, rather than the everyday currency of the political marketplace, are seen as unholy betrayals.
It isn't obvious how we could reverse the damaging course we're on. But a start would be to stop assuming that absolutely every democratizing reform we dream up will automatically make our politics healthier.
