The crafty republican elite has enlisted the assistance of those who will be willing to Bork Trump. Borking is an insidious undermining of anyone the Progresives want to diminish or destroy. In this case Trump, because Hillary fears what Trump will do to her in debate.
Republicans who will not stand with a solid republican contender are falling into the anti-Trump trap of the elites and the progressive democrats. Without Trump the Republicans will lose.
Trump won’t play by the rules in any debate with Clinton. He’s a wild card and they know it.
The establishment truly hates trump. They want to stay on their gravy train.
