We disagree. I believe Cruz is eligible.
His mother was a US citizen and of age when he was born. despite being born in Canada, with his mother being an of age US citizen meeting the other criteria of residency in the US, he became a natural born citizen.
A good comparison would be against Obama if he were born in Kenya.
His mother was a US citizen, but at the time of his birth I do not think she met either the age, or amount of time in residency in the US.
Which is why they have gone to such extremes to says he was born in Hawaii.
Anyhow, I respect your right to disagree with that.
But I believe if it goes to court, that the Supreme Court will find him eligible for the reasons I just gave.
And perhaps that will happen.
Trump himself, early in the campaign, before Cruz started doing well, indicated that his lawyers had looked at it and that his lawyers told him there was no problem. I believe he actually said this in the 1st debate.
Later, when Cruz started doing better, Trump opened this back up. And in that debate when questioned why, to his credit he said that it was because Cruz was doing better.
Anyhow, a Trump/Cruz ticket would do all of the things I mentioned earlier. And since I believe he is eligible, I would support it.
If the Supreme Court ruled differently, that would be a different matter.
Perhaps we will get the chance to find out.
That is how your plan would break down.
