I would think this is easy to calculate. Unfortunately my grasp of advanced economics is minimal.
GWB was elected in 2000. At one point he lowered tax rated and eliminated taxes for those earning a certain dollar figure.
So how did GWB fare when tax rates were lowered? Did revenue go up? I think it is a simple answer. Then we should calculate what happened when the Democrats took over the house in 2007.
Thoughts?
