Violence is much less likely if Trumps wins then if Trump loses.
The Left has created a PR Trump that does not exist outside anywhere but their own feverish swamp PR machine. If they cannot get people out of vote for Hillary, they are not going to get them to go riot for her. Once the reality of Trump as President dispel the rabid lying myths about Trump the Leftist propaganda machine have manufactured, there is going to be a lot less angst toward Trump among the Center-Left average people.
With Hillary, we know we have a corrupt lying, narcissistic megalomaniac who has no moral or ethical restraints on her lust for power. We know that ultimately only the people can impose restraint on a corrupt out of control government.
Thomas Jefferson said it:
“If a law is unjust, a man is not only right to disobey it, he is obligated to do so”
That's a really good point.
If Trump hires good people, gets good advice, and settles down into governing as a center-right President, the moderate middle will realize it was all manufactured outrage. With any luck, they'll turn on the manufacturers, which leads me to my new meme:
He has to find a way to do it without appearing to be petty or thin-skinned. But, he shouldn't let it go unanswered.
