Historically it has been done that way if you want your ass handed to you in the General. Which seems to be the plan here.
The true nastycruzers can't handle that simple truth... :)
Well obviously that's not true, since historically this is how it was done, parties picked their own nominees, and they did go on to win elections.
If there's a plan to lose in the general over this it is Trump's plan. He's getting it done by convincing people he's being cheated and telling other lies. The only thing Trump cares about is Trump. If he doesn't win he doesn't give a damn if Hillary or Bernie do.
And he's not going to do all the things his followers expect of him even if he did win. Most of what he says is nonsense, or stuff that he'd have no power to accomplish, but he doesn't mean any of it anyway. He just wants people to appreciate him. It's all about Trump.
Once we get past the convention, if he makes it, he's going to need the non-Republicans to appreciate him. Wait and see how fast his "positions" change. Hell, he's told you people this already.
