The moaning RINOs is a problem for Trump:
... How will Donald Trumps positions and rhetoric be treated by journalists who think of themselves as nonpartisan and subscribe to these professional norms? The big thing determining if his assertions are treated as in the sphere of controversy or rejected as belonging to the sphere of deviance is whether other prominent Republicans support him on a daily basis.
If they do, journalists will feel obligated to treat Trump as a normal candidate. They will cover both sides of the issue equally such as whether Mexican immigrants are rapists, if Trump can build a wall and get Mexico to pay for it, or if the US should ban all Muslim immigration. Trumps view would be treated as the Republican position and the other side as the Democratic position.
In Hallins terms, these issues will be in the sphere of controversy. However, if national Republicans regularly fail to agree with Trump and often criticize him, his positions will be treated as in the sphere of deviance...

Of course the media wouldnt be fair to him anyway but this makes it easier to demean him and his (our) issues.
No, Cruz, Kasich, etc. need to be dealt with now. They need to be shut up and marginalized as the dishonorable people they are. He cannot focus on the general with constant backbiting from them. That weakens his shots at Hillary, in essense, they are supporting her.
AS ARE their supporters that keep excusing their behavior.
How in the world can you fight the people in front of you when your so-called allies are stabbing you in the back!
Trump can multitask!
That is what he is doing, you just want him to leave your heroes alone, but they are the worst kind of enemy because the are inside the gate.
