The CBO has a horrible history of forecasting through recessions. Their one year numbers are fairly accurate as one would expect. After one year they have problems and are statistically way off from random walk forecast (see link below). I think the CBO tries to do a good job but if their GDP numbers are off by a few basis points everything is out the window. Plus things like supplemental spending cannot be factored into the equation because it is an unknown.
When are you coming home?
