The Congressional Budget Office just estimated that H.R.1, the House version of the American Recovery and Reinvestment Act of 2009 will add $169.5 b. of deficit/stimulus in FY09 and $356.0 b. in FY10, assuming a mid-February effective date.  The total 10-year cost is estimated at $815.9 b., so 64.4% would be spent or reach taxpayers within the first 18 months after enactment.  This is better than initial estimates, which showed about 40% going out over the same period.  The House plans to pass the bill late Wednesday, and the Senate hopes to follow suit next week.
