How on Earth are the Republicans not friendly to Catholics? Not only do they have about half of Catholic voters but the evangelical religious right voters even backed one as their candidate in 2012.
BRTD, I doubt most of the GOP primary voters knew Santorum is Catholic. The crap that spews from his mouth is the same stuff the right-wing evangelicals have been at for decades. Even living in the Philadelphia media market, I've always had to be reminded he's not a Protestant because he looks and talks exactly like one. Not only that, but past Catholic candidates have been OBVIOUSLY Catholic. The Kennedys, Kerry, etc.
