As with many of the other candidates, Cruz is probably there to push the agenda. I suspect a lot of those candidates are angling for appointments in a GOP administration more than anything else.
This iirc because it is in the body of the constitution needs to be addressed thru the court.
The issue doesn't have to go to court, it can go to GOP. It can go the state election boards, there are all sorts of places this can be challenged. Somebody certified eligibility, that's a misdemeanor.
And then there is the press - if a presstitute would assert the meaning of Rogers v. Bellei, a man born in Italy to a US citizen mother and Italian father is naturalized without going through an application and approval process, then why isn't Ted Cruz? Just the frickin' press asking that would change the dynamic, and the press is about as far from the court as one can get.
I lack creativity. It takes me awhile to see how all the pieces of the machine work together. But never mind me, what affects the outcome is the conduct of a nation full of morons (bless their hearts, they truly are good, honest people for the most part, and I mean no disrepect, just observing public discourse) who prefer to flap their uninformed gums.
