I see that Right wing sites, and conservative Catholic blogs are crowing about Trump doing well with Catholics, although the current analysis is based on exit polls which, I thought, had been shown up again as not that accurate. Anyway, this is despite evidence from before the election that Trump was not doing well with Catholics.
The Tablet provides a little bit more perspective - pointing out that Trump did well with white Catholics:
Actually, he did as well as Romney did with the white Catholic vote - something that I hadn't realised before.
But Hispanics - still a long way to go to convince a majority of them.
The Tablet also notes in another article that, when it comes to "liberal" referenda which the Church was against, they were still nearly all passed, which suggests that the power of the conservative Catholic vote is not what Conservative Catholics think it's cracked up to be.
So, there is this ongoing difficult question of whether this Catholic vote is coming from mere "cultural Catholics", or actively practising ones. There is strong evidence, of course, that a small minority of even Mass attending Catholics adhere to the Church's teaching on reproductive health; despite pockets of Conservative Catholic leadership (Cardinal Burke has announced his pleasure at Trump's win, for example), there is a pretty good case that the congregations are quite liberal. But it is not that easy to find research which differentiates between types of Catholics.
Hence, I would be interested to see more research on this topic.
And on a final note: look how consistent the Jewish vote is for Democrats in that graphic above. Jewish neighbourhoods in the States are not going to be happy at the moment.
