CBO numbers show budget challenge

Politico reports:

New estimates by the Congressional Budget Office released Monday underscore the difficult tax fight ahead as Democrats and the White House each promise voters that they can balance the government’s books by 2012.

From 2009 to 2013, the cumulative deficit under President Bush’s new budget plan would be $336 billion higher than the deficit projected by CBO under its own baseline, which assumes little change from current law over the same five-year period.
