Nonsense. Catholics, like Jews, mostly vote left. Thanks, Vatican II. I can remember when Catholics actually were conservatives. Some of my over 65 friends still are. But, today you have to stick cotton in your ears at Mass not to hear non stop left-wing propaganda.
Depends on the Mass...
Before Vatican II, the Catholic vote had never gone republican, with the possible election that pollsters argue about, the 1956 reelection of Eisenhower.
