The first half of Catch 44 is spot on.  The second, not so much.  That there are lines that each GOP "member" has that exceed the many cultural boundaries is a plus.  From that, sanity be brought back to the party.  And a healthy democracy needs a spectrum of approaches and governing principles.  No one party has a lock on good governance.  It's been understood that a Trump nomination would crash the GOP, now the nuances are coming out.  A significant one is how long prominent party members stay the course before condemning Trump.  Simply put, the longer the more damage.  It's all on record and can only serve as a campaign cudgel.  It's just how yuge the cudgel.
