Hillary’s Catholic problem?

If you do an online search for "Donald Trump Catholic problem," you'll see the media has run this story everywhere; post and tweet, rinse and repeat. See, e.g., National Review, July 18: "Donald Trump's Catholic problem"; Forbes, Aug. 23: "Trump has a Catholic problem"; Patch.com, Aug. 29: "Donald Trump's Catholic Problem"; New York Magazine, Aug. 30: "Trump has a Catholic problem. But how bad is it?"; and The Washington Post, Aug. 30: "Donald Trump has a massive Catholic problem."
Catholic voters are kind of like "moderate" Republican primary candidates: The media loves to trot them out while they're useful. But once that's done, the long knives come out. Thus, for a group that despises Donald Trump the way the press does, Catholics suddenly become a terribly important constituency. (Once the presidential election is over, Catholics' pesky opposition to abortion, assisted suicide and sexual activity outside of heterosexual marriage will again make them anathema.)
