From the WSJ editorial page:
Only a small share of the spending will occur in 2009, even though Keynesians would argue that stimulus spending should be frontloaded to kick-start growth. The Congressional Budget Office estimates that the largest share of the spending will occur in 2010, with the amount in 2011 being slightly larger than in 2009. Again, the timing exacerbates the problem: It will be tough to cut back on spending written into budgets as far out as 2011.
