Its not a Republican claim most of his forcasts have been well off. even the CBO says it doesn't add up. David Walker, the former chief of the Government Accountability Office also said it doesn't add up
"I don’t know why he made it. Politicians are good at making these type of promises during campaigns. Anybody that passed basic math would have known that you cannot end up dealing with our structural problems in our deficits without having more revenues."

"The nonpartisan Congressional Budget Office (CBO) says that President Obama’s budget and deficit projections are too low. The president’s budget will incur $9.3 trillion in federal deficits between 2010 and 2019 --$2.3 trillion higher than Obama had originally claimed.
The CBO’s latest analysis, released Friday, showed that the president’s proposed budget will increase the deficit to $1.8 trillion in 2009; $1.4 trillion in 2010; and $970 billion in 2011 -- falling to $658 billion in 2012 before rising again to $1.2 trillion in 2019.
The total deficit from 2010 to 2019 was pegged at $9.3 trillion."

Unless you can prove David Walker and the CBO wrong then Obama is using fuzzy math.
Why is it that when ever I ask you to name your source, you eith ask me to name mine, you say you already did or you change the question?
CNS (Conservative News Source) is a very biased publication. The differences is in the assumptions. And frankly Obama's assumptions make a lot of sense versus those used by the CBO. First Obama uses a economic growth rate .4 percent greater than that used by the CBO. Two, the CBO ignores any savings generated by healthcare reform. It adds all of the costs of heathcare reform but none of the cost savings. The CBO is not always right either.

How accurate are CBO's budget projections?
By statute, CBO's baseline projections must estimate the future paths of federal spending and revenues under current law and policies. The baseline is therefore not intended to be a prediction of future budgetary outcomes; instead, it is meant to serve as a neutral benchmark that lawmakers can use to measure the effects of proposed changes to spending and taxes. So for that reason and others, actual budgetary outcomes are almost certain to differ from CBO's baseline projections.
