Private forecasters unanimously believe that fiscal stimulus can temporarily boost growth. They give no credence whatsoever to the various right-wing alternative models in which foscal stimulus does not boost growth. Moreover, in 2001, when the objective case for fiscal stimulus was much weaker, there was no real debate about the efficacy of fiscal stimulus. The fact that Republicans are fiercely contesting the merits of fiscal stimulus now, while almost nobody was doing so when the case was much weaker in 2001, suggests that the right's skepticism is a political phenomenon.
