One reason Donald Trump was able to put together a coalition big enough to get him elected as president was that there were so many single issues about which different groups of people were exercised. They cared much more deeply about that one issue than a whole range of other issues, on which they may have disagreed with the Republican nominee. This is one explanation for Trump’s lead among Catholics.

Particular concerns among Catholics included life issues, of course. Many people voted against Hillary Clinton despite disagreeing strongly with Trump’s personal behaviour among women or with his views on globalisation.
