We are a week away from the 2010 U.S. midterm elections. The outcome is already locked in. Whether the Republicans take the House or the Senate is close to immaterial. It is almost certain that the dynamics of American domestic politics will change. The Democrats will lose their ability to impose cloture in the Senate and thereby shut off debate. Whether they lose the House or not, the Democrats will lose the ability to pass legislation at the will of the House Democratic leadership. The large majority held by the Democrats will be gone, and party discipline will not be strong enough (it never is) to prevent some defections.
