"Will the left listen or, as many believe it will, continue its tantrums?"
Considering that Trump and his more, shall we say ardent supporters were not going to accept the results of a "rigged" election and were openly speaking of armed action, the "lefts" tantrums are just that, tantrums.
It's odd that the writer speaks of the right roaring, when in fact, if you look at the numbers, this was not a victory wrought by the right, and I'm speaking of the clamouring mobs of Trump faithful howling for HRCs blood, chanting to "build that wall" and kick out the Muslims.  That core was always there, and Trump ate their adoration up at his rallies.  The reality is that the popular vote didn't change that much, and what got him elected was the middle ground that was turned off by HRCs elite persona.  
These are not the people going to Trumps rallies, they are too busy working, trying to get by.  
Trump ignores them at his peril.
