Chest thumping against his mortal enemies (reporters) is human.  Trump did it in a more bombastic but ultimately showman style more entertaining way.  How he will take a more entertaining verbal/twitter slap against the Thespians in hollywood next?  Basically all the gatekeepers of american culture were vanquished in this election and they are inconsolable.

Obama said "elections have consequences" and "I won" against the members of congress and the senate from the other party --- and he paid for it in 2010 by the voters taking away their supermajority in the senate --- because it was not entertaining.  If Obama had figured out a way to say "look, you guys screwed up the country, I'm going to fix it" and followed through and succeeded, 2010, 2012, 2014, 2016 would have seen the republicans wiped out.

The shoe is on the other foot, if Trump did actually find a way to prove macroeconomists and slide rule gurus wrong and create good jobs, the dems are toast.  If he fails, he's toast.
