> So rather than introspection and analyzing why they lost working class voters (black, white, etc.), for example we saw party reg changes in the primaries favor Repubs, why are so many people mesmerized on this one theme?

This is very dishonest. Evey article analysing the election results is talking about the working class, Hillary's arrogance, the DNC and so on. The fact that people are also talking about the explosion of fake news around the elections doesn't mean people aren't also talking about other issues.
