Santorum is NOT a conservative politician. It is misleading to call Santorum "conservative". He may be a moral man but as a politician he is a spender and tries to go along (like Bush did). Santorum (again like Bush) would be unable to veto any spending bill. To be a fiscal conservative politician, you have to be able to veto and veto again and veto yet again until they give you the very limited spending you want. Gingrich is or can be a conservative politician.
The veto, and only the veto can bring spending under control. Bush refused to do it. Obama refuses to do it. Spending will remain out of control until they get a backbone and VETO bills.
Newt Gingrich is a Hard-Core Conservative.
Santorum is better than Gingrich on this ranking.
Santorum's lifetime ACU rating is within two points of Gingrich's lifetime ACU rating (88.1 to 89.9).
