Only Newt and Paul are credible on spending, Paul way more so than Newt since Newt in the last 10 years or so has been making lots of big government sounds. Santorum has zero credibility and is unacceptable.

But as far as specific proposals go, all of them are promising dramatic spending cuts.
Except Romney, who says we should only have “reasonable” cuts of $500 billion over 5 years.
