It wasn't because they were Catholic, either.
150 years? Well, that flanges up with what I said, doesn't it?
If you want to get the GOP more votes, dismissing demographics isn't the way to go about it. Understand the underlying problems and there might be a solution. Fail to do so and you only guarantee failure.
Perhaps that might be more successful than painting all Catholics (including Conservative Republican Catholics) with a millions wide brush because some are (at some point) liberal or side with those who side with liberals.
Dismissing the secular factors in the voting habits of a demographic (actually, a few demographics) makes as much sense as writing off the Women's vote because there are a lot of Liberal Women out there. You are concentrating on the wrong factor, it is that they are Liberal or Democrat that is the problem, not that they happen to be Catholic.
Nobody is dismissing demographics, I am trying to educate people in them, members of the catholic religion always have and always will vote majority democrat, that is important demographic information, the most important since the 1965 immigration act was written to import millions of them to replace the anti-democrat voting Protestants.
What is the pro-abortion/gay left’s hope for Texas? That it becomes Catholic, as California did.
