He only represents the president's party. It's a testament to Clinton's astuteness and skill that he planted the word there without anyone noticing. I don't know, and neither do you. That's the point. There are no absolute laws in politics or any other social science.
Laws operate only within certain parameters and under certain conditions.
Those parameters and conditions, in turn, are subject to human intervention. In this case, the weak link in the law is perception. If I fail to see prosperity in its historical context, or to associate it with elections, or to think of Bush and Gore in terms of their parties, I won't vote the way the theory predicts. Somebody has to step in and make me see things that way. That's what Clinton is trying to do.
