Someonew has given you bad information, FRiend. Sntorum’s voting record is LESS conservative than Gingrich’s, In 1994 for example, Newt had a 100% ACU score, compared to Santorum’s 94%. Even Ron Paul had a higher score (88%) than Santorum that year, LOL.

That’s cherry-picking certain years. Here’s the best way to compare if you are using ACU as a ruler:
Santorum: Lifetime ACU rating 88
Ron Paul: Lifetime ACU rating 82
Gingrich: Lifetime ACU rating 90
Joe Scarborough: Lifetime ACU rating 95
