My assessment of Santorum’s intellect has nothing to do with him being sweet or shunning sin, it has to do with watching him for over 12 years as my Senator and 6 years since. The guy’s not a dullard, but he is not remotely a mental giant, and certainly nowhere near the level of intellect that Ronald Reagan was, or Newt Gingrich is.
Excuse me, but a mental giant would not get divorced and remarried multiple times, cheating all the while, and then run for POTUS!
