Yet it is an iron law in democracies that anything achieved through movement politics can be undone through institutional politics. The reverse is not the case. The movements that reshaped our country over the last half century did much good, especially in changing, as we say, hearts and minds… But over the long term they are incapable of achieving concrete political ends on their own. They need system politicians and public officials sympathetic to movement aims but willing to engage in the slow, patient work of campaigning for office, drawing up legislation, making trades to get it passed, and then overseeing bureaucracies to see that it is enforced.
