If the GOP nominates Cruz they will be be driving the final nail in the natural born clause. Any party that would do such a thing deserves no support.

That’s the way I feel on the basis of the RNC allowing Cruz to even run. The party objects to the NBC clause, and likely other parts of the constitution as well, and is duplicitous about its goals.
