Catholics have always voted democrat (with a handful of exceptions), including before the recent influx of Hispanic members of the Christian denomination.
You just lived through the best Catholic voting period of American history, the Catholic vote went republican for the first time, in 1972, (with the probable exception of 1956 when many or most sources think that they voted republican) Catholics voted republican 4 more times during the 40 years after that.
It looks like that history thwarting period is over, as the Catholic vote returns to it’s normal place in American politics.
“Catholic” doesn’t mean anything anymore. My point is that WHITE, PRACTICING — actually practicing — Catholics are already mostly Republican and that number is growing.
