Catholics do vote democrat and always have, with the exceptions of five times, that means all those generations of white Catholics until Hispanics started showing up in large numbers recently.
While whites have been leaving the Catholic denomination for years, even in 2012, when Obama was declaring war against Christians and Catholics claimed to be outraged and under attack, white Catholics only went 59% republican, as the article points out, a record, in 2008 it was only 52% for white Catholics, this is while our second largest denomination in America votes 80% and more, republican.
Besides, the internals of the Catholic vote is meaningless as we import millions more, and the Catholic vote will continue to be what it has always been, Democrat.
Nice axe...
