This will be big fuel for the GOP:

The Congressional Budget Office (CBO) corrected its estimate of the Senate health bill’s costs on Sunday, saying it would reduce deficits slightly less than they’d predicted.

In a letter to Senate Majority Leader Harry Reid (D-Nev.), CBO Director Douglas Elmendorf said that the nonpartisan budget office had overestimated the extent to which the legislation’s new Independent Payment Advisory Board would bring down the deficit.

While the CBO’s estimates of the board’s and overall bill’s impact in its first 10 years of the legislation are correct, Elmendorf wrote, the program’s effects on deficit reduction during the second decade of the program were overestimated.

I’m waiting for the press releases from the GOP to start flowing in any minute now.
