Actually, this is not a "birther" issue. The Obama birther issue centered around whether he was born in the U.S. -- that's where it became the stuff of conspiracy theorists and general loopiness. However, it is undisputed that Cruz was not born in the U.S.
So we just have the pure legal issue without the birther looniness: Is someone born abroad to at least one U.S. citizen parent a "natural born" citizen for the purposes of presidential eligibility. You'll read over and over that "most legal experts" think so. But that doesn't mean it's been decided. The only "legal experts" who count are the nine in SCOTUS.
It would seem that the legislature has clarified this issue a few times already, and we have precedent with English law that children of citizens born abroad are citizens at birth (Natural Born, God-made) as opposed to naturalized (by the state or man). If there is even a shred of evidence that Ted Cruz was ever naturalized, then you have something. Otherwise, its a bunch of election deception. His place of birth has never been hidden or in question.
I think we put too much already in the hands of unelected judges, especially when it is WE THE PEOPLE through our representatives who make law. The judiciary has grown far more powerful than the Framers ever intended. I would rather not give them any chance to legislate/pontificate from the bench, or any more power than what the Constitution allows. Until some of the nutcases sitting on the bench now are retired, I would prefer to keep everything out of their hands.
The Birther issue with Obama went way beyond the place of birth. His whole nativity story was an ever changing narrative designed to confuse the issue and discredit anyone searching for the truth. We may never know the real story.
