My oldest daughter and son were also born in Bangkok Thailand and are citizens. American father, Thai mother who has since become a citizen. A lot of people seem to think one must be born within the confines of the U.S. border. That's not the case. We've had some presidential candidate born outside the borders.

George Romney Mexico
Goldwater, Arizona Territory
McCain, Panama
Cruz, Canada
Gabbard, American Samoa

There may be others, but these come readily to mind. This controversy will probably rage until the SCOTUS actually rules on what a natural born citizen is.

As far as I know, being born overseas is no big thing as long as one parent is a U.S. Citizen. That automatically makes the child a U.S. Citizen. Now naturally born, most constitutional scholars seems to think so. Not all, but a good majority. We really won't know until the SCOTUS rules.

It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
