>>And that my friends exposes the corruption in the primary process.<<
It does nothing of the sort, but your comment exposes your devotion to your dear leader. Trump whines and tells you something is corrupt (it couldn’t be his incompetence, after all) and you obediently go forth and spread the word. Try thinking for yourself for a change because if you don’t you’re going to someday find yourself part of a mob, a part you won’t be proud of when looking back at it much later.
But to your point. The GOP is selecting its own candidate using rules established in individual states. The party has every right to use those rules to try to avoid the nomination of a person with unfavorables so high that it’s would be foolhardy to place him on the ballot in November. The fact that they’ve swallowed hard and now appear to be willing to back an outsider like Cruz in an effort to avoid nominating Trump should be viewed as a conservative success story, but that story is lost on Trump followers. Instead they join him in whining “Cheaters!” That’s utter nonsense, and you should know that.
Thank you for inadvertently making my point.
