"A New Era Of Responsibility" II

Megan challenges Obama's honesty:

Obama is getting a lot of credit for projecting out ten years, I'm not sure I see the point from an economic, rather than a political, perspective.  These models consist of the modellers assuming that most things will continue to be largely as they are, unless the economy is in a recession, in which case everything will return to 3% trend growth 18 months after the recession started.  They don't track reality all that much better than you would by throwing darts at a board with a bounded range of GDP growth around a mean of 3%.  Given that we are in most unusual times, they are particularly suspect now.
