Before the nineteen-seventies, most Republicans in Washington accepted the institutions of the welfare state, and most Democrats agreed with the logic of the Cold War. Despite the passions over various issues, government functioned pretty well. Legislators routinely crossed party lines when they voted, and when they drank; filibusters in the Senate were reserved for the biggest bills; think tanks produced independent research, not partisan talking points. The "D." or "R." after a politician's name did not tell you what he thought about everything, or everything you thought about him.
