Nate Silver offers a preview:
Suppose that the economy is showing relatively robust signs of recovery by 2012: not necessarily spectacular rates of growth (in which case, Mr. Obama’s re-election might be almost a sure thing), but G.D.P. growth on the order of 3 or 3.5 percent, and a reasonably significant reduction in unemployment. (Most economists do think that the deal will have some stimulative effect.)
See, this is proof that lower taxes work, I would argue if I were a Republican.
The stimulus all that government spending didn’t work. It just increased unemployment. But keeping taxes low worked, and the economy is finally recovering. So why on earth would we want to raise anyone’s taxes now?
