While they don’t have to stick their necks out they are going out of their way to denounce Trump. Personally I don’t think they have enough of a following that their “endorsement” makes a difference. Who the hell do they think they are that to believe that people will blindly vote for who they endorse? That’s anohter symptom of their arrogance. The GOPe is so arrogant and out of touch it’s unbelievable.
Part of Trump's appeal to a lot of us (including me) is that he wasn't a political insider. The good part of that is that he doesn't owe people favors. The downside is that nobody owes HIM favors, either.
