Shortly before the election of 2016, Bernstein made a big deal of comparing it to the Battle of Gettysburg.  He said the election would be the decisive battle in the culture war.  

Now that his side lost that decisive battle, they cannot accept defeat.  Even with Soros, the mainstream media, and much more money, Hillary lost to Trump.  There aren't competing truths here.  Bernstein's side lost and the truth that America is a center-right country is something they refuse to acknowledge.
