The point is that there are too many other variables. If you don't control for the other variables, you can not, as a true scientist or statistician, draw any conclusions.

And, believe me, I want this to be true. Yes, there are a lot of variables changing all the time - which leads me to ask why would all these disparate variables all allign in certain ways during periods of Democratic rule and Republican rule and led to this steady statistical regularity?

again, if things are so outside the control of party, why should we get sucha clear distinction, for example, in growth rates at the very bottom, over a 50 year period?
