The Post suggests that the Center's analysis is based on a rosy forecast because the forecast assumes steady economic growth and doesn't assume the outbreak of new wars. But, there is no CBPP forecast reflected in our analysis; we simply used the Congressional Budget Office's (CBO) economic and fiscal forecast -- as such fiscal organizations as the Concord Coalition, the Bipartisan Policy Center, and the Committee for a Responsible Federal Budget, among others, do.  The Post might have informed its readers of that fact.
