No one disputes Cruz is a "naturalized' citizen. The issue is whether he is "natural born," which is the the only relevant constitutional standard operative here. It's a vexing issue; it has never been litigated before. I'm not sure what the result would be if Cruz gets the nomination and the Dems file suit claiming he's not eligible to be president. I could see it going either way depending on the judge. It's scary.
I like Cruz and think he'd be a great president. But this issue has the potential to be a mess.
Consequently, I am considering supporting Trump, but only because of his proposed ban on muzzie immigration. We need to ban muslims from entering the US. If not, expect many murderous attacks on jews in the US. I believe Trump would get very tough on muzzies should this happen.
