Which policy do you support for the U.S. government policy?  More importantly, Why?

Most governments in advanced economies have expanded government’s spending.  But in some cases, espeically in the Euro area, expansionary fiscal policy has been one of most controversial policy issues.  Of course, a similar debate has been going on here in the United States.  Can you identify key politics groups (proponents & antigonists) on the fiscal policy issue in the U.S.?  What are their distinctive logics to support their policy position?  Which one do you support?
