It is hard to overstate just much the entire Washington/New York political establishment, which includes the Federal bureaucracy, the "elite" media and the educational institutions all absolutely loathe Donald Trump.
Sure, you knew that. But it is the depth of the disgust, fear and loathing that you have to experience in person to believe. I have had the misfortune of such experience, and it is stunning to see how otherwise intelligent and educated human beings can go absolutely berserk and apoplectic at the slightest mention of Trump's name or the mildest implication that you might actually agree with him about anything whatsoever.
So, when he issues these Tweets to his followers, Trump produces an outpouring of mad dog, mouth-frothing rage unlike anyone else. And because he understands that, I believe that he issues them in a manner intended to troll and taunt. This tactic seems to equally affect both liberals and Beltway/New York conservative pundits, who mistake trolling for dumb bluster, and nods and winks to supporters as evidence of a deeply unserious intellect.
And yet, he continues to quietly do the right things while leading his adversaries on one wild goose chase after another.
