Sounds like a subtle threat to me. The GOP-e has a plan for Cruz and they will make NBC an issue.
Seems to me that the discussion on every news site proves Cruz correct. He placed the weaknesses of ObamaCare front and center while the rinos were weeping for a way to kiss the emperor’s feet.
In reality, iirc, Cruz has a better case than did McCain, for McCain’s Panamanian birth, by the law of the time, called into question his born-American status.
