Alright, but unlike the Rick rollers, I'll admit that Newt ain't been perfect on every single vote. That said, he left Congress with a 100% ACU rating, while Santo left with a score of 88%.
Santo also didn't have a leadership roll in Congress, like Newt did. Newt's got some actual accomplishments under his belt, and they were large. Ricky? Not so much. Not even close.
If by, "left with" you mean their respective ratings for their last year in office you're right. That's like saying Hank Aaron "left MLB with" 10 home runs (1976, his last year).
IMHO, a more realistic use of the term "left with" would be their aggregate lifetime ratings for their congressional careers which puts Newt at 90% and Santorum at 88.1%. Given that Newt was a Representative from a safe conservative district, and Rick was a Senator from a swing state, the only really shocking thing about that comparison is why Newt's wasn't much higher....
