There is a rule of headlines which says that for any which asks a question, the answer is "no." That's fair, and I don't mind running against that. I write this more to note that the question would have been impossible to even ask until quite recently, and to wonder if this is a trend.
The amazingly ignorant statements by Kamala Harris and others, suggesting that the Knights of Columbus is an alt-right organisation, or the easy attacks on Catholic high school students, and the very calculated attacks on Roman Catholic as judges - from lapsed Catholics like Pelosi, in order to paint the others as fanatics - causes me to wonder what is up. It struck me a suicidal at first, because I am so aware of the importance of Irish Catholics to the Democrats in New England, especially Massachusetts. I have known people who let me know angrily and bitterly that they would never vote for a Republican because of what Protestants had done to their families in the 50's - or the 20's. The Kennedys were not unusual for Massachusetts, but utterly representative. I understand it is the same in Chicago, and would therefore bet that Irish Catholics were strongly Democratic in other cities as well.
There has been some puzzling over the years why Irish and other ethnic Catholics have remained loyal to the Democrats all these decades when they have been so clearly the more abortion-friendly party, and the usual explanation is how successful the Democrats have been at framing it as something that I Myself Find Clearly Wrong, but not something to be required of others in a diverse society. This has been a successful strategy among African-Americans as well. My own take is that this is evidence that identifying with a culture as a whole is more important than any part of it, even its religion. Yet whatever the reason, the thing is a fact, at least in my neck of the woods. Even The Dropkick Murphys and the rough youth of Quincy, who you might think would at least consider the anti-elitist appeal of Donald Trump, remain aggressively Democrat. Because that's who they are.
It was a thing, at least. Maybe that is not so true now. My examples are of people my age or older, and I am no longer young. The old Irish Democrats are not going to change no matter what you do to them now, and the younger ones no longer attend Mass all that often. Perhaps they are easily persuaded that Catholicism is a separable piece, and old-fashioned (the horror!). I don't have my finger on the pulse of that at all.
One would think this is ripe for ridicule. Is Notre Dame an alt-right school? Is Boston College, where John Kerry got his law degree, now a dangerous place? The colleges may get a pass, of course, because Catholic colleges are not always very Catholic anymore. Georgetown comes to mind. They seem to have been co-opted into the religion of liberalism.
