True. But his mother was American, which means he's eligible.
That will doubtless be news to a certain set of morons who know who they are and will self-identify in due course.
Cruz is certainly a citizen and has been one for more than long enough to be eligible to the Senate and the Supreme Court, but not the presidency - but then neither were McCain or Obama eligible to the presidency and that didn't bother the Republican or Democrat leadership. Neither are Rubio or Jindal, but If we want a conservative Hispanic President Suzanna Martinez is not the only possibility, but certainly one I'd vote for if she could get by the Rino block.
Perhaps Cruz will have the courage to cite and explain the common law and precedent next time his party decides its time to ignore the Constitution because its party's war horse feels entitled, in spite of the Constitution. Rinos did their best to block his candidacy. He might be inclined to nail the country club republicans with the truth that had they not supported the ineligible McCain, with major help from the Obama campaign committee, who sponsored two Senate bills, SB 2678 and SR 511 in Februrary and April 2008 respectively, to imply they had rectified McCain's ineligibility, they might have done their job and vetted Obama, born to an alien father and thus not a natural born citizen.
