from the limited time that i watched, both gingrich and romney did fine....santorum and gingrich had a rather substantive disagreement regarding pakistan.....all with the exception of paul were unequivocal in opposing a nuclear armed iran....and only paul was so confused to assert that waterboarding is torture without being able to define torture....further the exchange between the moderator and gingrich ie obama's targeting a us citizen was excellent and gingrich was correct.....
