Excellent analysis.  He's right on.  Like every reality TV show, the schtick simply loses its appeal.  It gets stale and the audience (and media) start to move on.  The show becomes ever more desperate until it jumps the shark.  The Trump Show has reached that turning point.  

The GOP  will trot out the usual proxies to try to defend Trump and whitewash his statements and hide him from the media to control the damage (remember Sarah Palin?).  But he won't be muzzled and real journalists, as well as the dems, aren't going going to him a free pass.  His past lies and activities are going to stick to him like velcro until the narrative about Hillary's dishonesty shifts to him in spades.  

By August all those republicans who jumped on the 'Trump endorsement train" are going to be desperate for a way off. Christie, Ryan, Sullivan, Murkowski and the rest... They gave their opponents a gift that'll keep on giving for years.  And it'll be a bloodbath in November.  

Popcorn anyone?
