Trump is not a conservative, my guess is Rush, Levin, etc, have known that all along but gave him a pass because he is so good at attacking the media and defying political correctness.
And that is all terrific about Trump, but he’s no conservative.
I noticed the change among the radio talkers when Trump tried to pull that birther slime on Cruz. Now that Cruz has shown he can beat Trump (note now Trump has lost and endlessly babbling about polls has less impact) and Rubio being pretty conservative on most issues, I think the Trump love is over.
Cruz is ineligible by any formulation of the definition the founding fathers would have used for "Natural Born citizen." Natural born status was always viewed as being transmitted paternally, not through the mother. All that said, the proposition that Rubio is a true conservative and Trump isn't is horribly stupid.
Trump is the only conservative on the issues that really matter; trade and immigration.
