My recollection is Trump started it with “he’s not a hero, heroes don’t get shot down comment. He also insulted mist of his republican opponents in a juvenile way. he emasculated jeb bush for instance. When you see how the Bushes respond it’s understandable. You can’t humiliate and insult people and expect their support.
Of course, the propaganda media wants you to think that. If you had read the accompanying article, you would see that McCain had recently called the people at a Trump rally the “crazies.” This happened only days before one of candidate DJT’s (in my opinion) worst errors. IIRC, he tried to smooth over that statement in his next sentence, probably realizing that his statement was in very poor taste. Of course, the propaganda media never writes the next sentence.
“You can’t humiliate and insult people and expect their support.”
Tell that to his co-candidates who do support him now, e.g., Carson, Cruz, and others. I think you CAN expect their support if supporting Trump is for the greater good, i.e., the survival of America. If those like McCain, Jeb and his family, et al., will allow a verbal insult to motivate them to take down this country, then there’s a special place in Hell for them.
Who of us hasn’t been insulted, humiliated, etc.? We cope.
