there is no middle ground

In her excellent biography of Coolidge, Amity Shlaes writes (p172):

Still, Coolidge felt certain of one thing.  The progressives could not be met.  Conciliation would not work.... This time, there was no middle ground.

The issues the progressives of the post WWI era were concerned with are vastly different than the issues modern progressives champion, but the lesson Coolidge learned in his time is no less applicable today.  There can be no compromise with the left.  There is no way to negotiate with them.  They will demonize anyone who stands in their way and will seek their destruction.  It makes no difference if the name is Trump or if the name is Brett Kavanaugh or Mitt Romney or Bush. 

Sadly, the right refuses to accept this reality, and as a result, will continue to lose.
