They sure do in New England. I have asked a couple of Catholics who have their head screwed on straight why that is true...they shrug and say "Got me..."
My Catholic neighbor is an alcoholic laid off union painter and he seldom votes at all but if he does he votes catholic. Another Catholic family we know willingly attends gay marriages and ALWAYS votes Democrat. They just hate those rich Republicans. It goes on and on.
My new term is "Low information Christians". They are turning this country into Europe.
