Aside from momentum, why keep it? What if we have a 20 year residency requirement, or even a requirement that the person had to have been living here before the age of 10 or something. Are we really worried about a person being a double agent or being raised in another country and then being sent here to ascend through the nearly impossible hoops required to become a presidential contender, and survive background scrutiny and everything else on the 1 in a million shot they become president? What's the point anymore?
I can see the flip side of that though. Imagine you were born in Country X, and spend the first 10 years of your life there. You remember the streets and you still remember the friends. That same country started a war on US, so you need authorize bombing of the country.
It could be a lot harder for you to do so if you consider that country to be your origin.
