So you agree that it would be up to the Supreme Court to decide the question of the eligibility of Senator Cruz to be President but that, unless it were a unanimous opinion, it would be “political.” How does that make Senator Cruz a good choice for the Republican nomination? From what you say if a split decision found him not eligible it would be “political” but he would still have to obey it.

No, I assume the Supreme Court should attempt to define a Natural Born Citizen. Then the question wouldn’t be revisited with every foreign candidate that comes along. But, if the decision is not 9-0, then it becomes a political decision and the question will still not be settled.
