Great, the problem for Cruz (if the constitution is followed) is that the constitution assigns US citizenship through jus soli.
If the only authority used for finding US citizenship is the US constitution, Cruz can only be a naturalized citizen.
So if your parents travel into Canada for the weekend and you’re unfortunately born there, you’re ineligible to be President.
You Sir, are correct! </Ed McMahon>
I’m sure this has been brought up, but if Cruz is eligible, any foreigner who has a US citizen parent is too. I’m also sure the hard Cruz fans will say this isn’t the case, but there’s no way we do not end up at that clearly dangerous place.
