that's not exactly the whole story. lots of US Catholics are still in the "honeymoon" period for this new pope and lots of uncritical Catholic support is no doubt coming from latin Catholics, which is to be expected since they consider him one of their own. i am personally concerned about what he's up to, but trying to give him the benefit of the doubt. he does appear to be insulated from hearing any opposing viewpoints. that's a problem.
Sure it’s the whole story, it is polling from a week or two ago.
The Pope holds the typical Catholic politics, and he has the high approval to prove it.
Only 4% of American Catholics disapprove of him.
