I think I know what Rush is feeling uneasy about.
If Cruz starts to rise, and Trump does not get the nomination, then Hitlery is president.
Going against the front-runner could mean throwing the election to the dems. Yet he likes Cruz. Does he throw in with Trump because it means big tent victory, or does he continue to support Cruz?
Crubio will not get the Trump votes. Not after yesterday.
I have sensed this too. Rush has been tottering on the fence, and its getting harder and harder to balance. I liked him much better when he was honest.
If Cruz starts to rise, and Trump does not get the nomination, then Hitlery is president.
This is what I have been saying. Cruz will not win.
