"Here’s another mystery: How could so many Roman Catholics and so many evangelical Christians – 80 per cent of the latter, it seems – vote for Donald Trump over Hillary Clinton? ...How could any woman vote against Hillary, let alone 53 per cent of white women?

In the case of many Christians, it's called abortion and other moral issues the Supreme Court makes decisions about. It is quite mind boggling that Mr Caplan can't even recognize what moral concerns move them or what they, as opposed to he or Mrs Clinton, perceive as their interests.  Their moral views may be wrong, but they aren't that hard to understand. Mr Trump was sinking in the polls with these groups after the Billy Bush tape and other revelations---until the emails brought the unsavoury Mr Weiner back into the picture and reminded Americans how Mrs Clinton, Nancy Pelosi,  Barbara Boxer and others condemning the unsavoury Mr Trump had earlier excused or overlooked the equally unsavoury sexual behaviour of Bill Clinton.
