In my opinion, the President. The Republican candidates are fixated on shrinking government for the sake of shrinking government, to the point where they seem unable to notice that the millions of government employees laid off over the past two years have been the biggest single contributer to unemployment, and the biggest single drag on the economic recovery.
Which wouldn't be quite so bad, if our structural deficit problems had actually been addressed. They haven't, because those problems don't result from overdone discretionary spending, which is what has been cut.
In essence, we've had the worst of both worlds, courtesy of a misguided House and an obstructionist Senate minority.
