Iraq War Teach-in

I went to an Iraq War teach-in. And the word "Weapons of Mass Destruction" was thrown around a lot. The thing with the word "Weapons of Mass Destruction" is that it can be a very vague term. Unless, you operationally define it. I mean a 100 or 200 lb bomb could be considered a weapon of mass destruction. So, one cannot really say that we haven't found weapons of mass destruction. Unless by weapons of mass destruction one is talking about nuclear weapons, then one can say we haven't found any. But it is a well-documented fact that Iraq had chemical weapons which can be considered weapons of mass destruction. And, we have found these chemical weapons in Iraq. But, how much will this affect the election?
