Newt Gingrich would add 7 trillion dollars to our debt, and Santorum would add 4.5 trillion dollars to our debt.
To show how fake Gingrich and Santorum as Conservatives; I will say, Mitt Romney's plans are more conservative. That's right, Mitt Romney would raise the debt 250 Billion dollars, which is only a fraction to Newt Gingrich's and Rick Santorum's plans as President.
Ron Paul is though, the only real conservative as he decreases the debt by 2.2 Trillion Dollars.
(this is all according to a budget watchdog group according to CNN)
