What we know is that republicans have won the Catholic vote 5 times in our history, and that the democrats have won the Protestant vote 3 times, 1932, 1936, and 1964.
Clinton, Clinton, Al Gore, Obama, Obama. are all normal Catholic voting, republicans may never win the Catholic vote again, those 5 times may never become 6.
Like I said church going Catholics and church going protestants vote the same way, and non-church going Catholics and protestants vote the same way. Makes no difference at all what demonination someone might be. Practicing christians do not vote democrat. End of story.
