Unfortunately, Bush's tricks are now Obama's tricks too. Just as Bush put out budgets that had little to do with reality (especially regarding projected deficits and using unrealistically rosy best-case scenario projections) Obama's Medicare cost projections are dangerously unrealistic. Medicare's chief actuary says: "There is a strong likelihood that the cost projections in the new trustees report under current law understate the actual future cost that Medicare will face. A strong likelihood." More here.
If Bush's budget fantasies bothered you - and they should have - then so should this.
