IMO the founding fathers meant for there to be a higher level of "citizenship" established for someone running for POTUS than someone establishing simple citizenship. If that is the case I am in complete agreement with our founding fathers.
For all the people who say YES just because his mother was a US citizen think about this. I'm assuming you are also saying YES to a situation where a female US "freedom fighter" who is a US citizen leaves the country to become a freedom fighter and becomes impregnated by a foreign ISIS terrorist. Under your idea their offspring would be eligible to run for the POTUS.
IDK about you but I'm not ok with that thought. Cruz? No thank you.
What about a mother who travels to Canada and delivers prematurely. That accident forever bars her child from serving as president? That's ridiculous. A child born to a "freedom fighter" is going to have some serious baggage to overcome in order to serve as president but why bar them? Sins of the mother?
