Once a politician has a record in office they can't hide behind platitudes. He has a very fine line to walk if he's at all interested in a second term. Hell, even Congress will have to watch themselves for their own collective sake.
More than half the Congress could shoot a person in broad daylight and still get reelected.
Ok, that's hyperbole, but once you survive your first reelection, you stand a very good chance of lifetime employment.
