He knows naturalization does not mean natural born. Naturalization comes from acts of Congress, natural born comes from two citizen parents born on US soil.
Why do you think Trump had that song ‘born in the USA’ played before his rallies. Sure was not because it was a patriotic song.
Naturalization only with regard to imposing a common rule. Natural-born refers to allegiance to someone. and that someone does not necessarily lose status just by residing abroad. They have to give it up. Sort of like if your wife moves out of your house she has to divorce you before she becomes your ex-wife. Any children she bears are your children.
