I agree. There was some examination of why he may have won in the first weeks after the election, but that aspect of the conversation has largely disappeared.
It's now all about the dark art of "fake news", almost as if, since he was elected illegitimately, none of the reasons he may have been elected matter.
I wonder if we'd even be having this discussion if Trump hadn't been elected. Probably at some level but not to the degree it has been.
