Rush’s policy is not to endorse either; he has spoken of Trump and Cruz approvingly, though in entirely different contexts.
It looks like Trump is destined to win, and to win before any convention. That happens by voters alone (getting over 1237, a possibility) or by voters plus negotiation before the convention.
I expect the GOPee to pull something, somehow, as their and their donors’ money pipe are threatened.
Rush just said a “hallmark of conservativism” is to “call attention to government failure” (which is true) and notes that Trump does this in his speeches.
He is open to both remaining “viable” candidates (and speaks dismissively of the Post Master Candidate).
Letting this play out.
The GOP is cursed by Keystone cops plague. Whatever they try turns to crap. No worries.
