The only Roman Catholic candidates are Rubio, Jeb, and Christie, so it's not like he had many choices.
It's not 1960. It isn't really a big deal whether someone is Catholic or Protestant (and Rubio does go to both churches).
I'd bet the Rickster cares though.
I am a bit surprised because I suspected Santorum could be a Trump guy for protectionist reasons, but apart from that the closest candidate to him ideologically is Rubio. Whatever Santorum's faults he never went around the twist in to anti-establishment-for-its-own-sake land like Huckabee.
