Ultimately, the only way to ensure that a future Congress follows orders—whether it's to eliminate the deficit or to punish banks or to implement immigration reform—is the old-fashioned way: Political pressure. Whether that pressure comes from K Street lobbyists or grass-roots campaigns, its purpose is to persuade Congress that this cause still matters. Deficit reduction will only happen if future Congresses are as scared of the issue as the present Congress. (The reasoning could go something like this: I don't like these tax hikes, either, but we need to do something about the deficit, and, besides, I didn't write this law.) Congress may not be able to bind itself, but politics can.
