House Budget Committee Chairman John Spratt (D-S.C.) said McCain's proposed budget is unlikely to balance the budget in four years, as the McCain camp claims, pointing to further tax cuts that Spratt says will add to future deficits.

"McCain is not just embracing [President] Bush, but all the Bush tax cuts and then some," Spratt said.

Obama spokesman Hari Sevugan said the numbers "don't add up," calling McCain's proposals "gimmickry" that do not address the "real math" of the budget.

Spratt, however, conceded the idea may work.

"Obviously if there is a substantial drawn down in Iraq," Spratt said, "there will be a peace dividend of some kind." Spratt said though that while a peace dividend may help erase deficits, the Department of Defense may soak up alloted funding to help recover from a war that has stretched personnel and resources.
