Ditto for my parents too. There are millions of elderly Catholic parents who share virtually the exact same social sentiments as WFB but still hate Republicans. I've often told my parents they must still believe FDR is the president. Their views of Democrats and Republicans haven't changed since I was a child in the fifties and sixties: Democrats are blessed by God, and Republicans are greedy, nasty spawns of Satan.
I read somewhere that nationally over 50% of Catholics vote consistently Democrat, and those that vote Republican are in the low 30%. Among older (as you say elderly Catholics), that number is upward of 80% who vote Democrat.
I had a dinner table conversation with my aunt and uncle (she Irish immigrant daughter and Catholic, he Italian immigrant son and Catholic).
I put very basic social questions before them, such as "Well, how do you feel about homosexual marriage and partial birth abortion?"
They were appalled I would even ask them these things, and told me how terrible each were. When I said the Democrats were the champions of both, they got very, very, very, very angry with me.
There is no reasoning with people who don't want to discuss truth and logic - especially if your opponent doesn't have the facts on his or her side.
