I don't argue with your points, but even Clinton was able to do some things in controling federal programs (i.e., sign some GOP bills) that neither Reagan nor Bush 43 have (welfare reform, etc.).
Remember when we had GOP majorities with a bit more of a spine, if not a very good PR program?
I remember the Grace Commission and a-lot of talk about "waste, fraud, and abuse," but I don't recall that panning out very well, back then.
I am not saying GW has not done good things and I intend on voting for him.
