Other nations citizenship statues have NOTHING to do if one is a U.S. citizen at birth or not.
Yes indeed, you are very wrong.
LOL ... who said they did?
His father was NOT an American citizen
of any kind. And our Constitution calls for
the “natural born citizen” requirement for
president and vice president.
His mother’s citizenship can feasibly have bore
on o’s status, but the fact that he was born of a
Kenyan or British citizen father casts a whole
additional wrench into the issue.
You might want to do some research on the
intentions of the Founders regarding their
strong opinions about dual allegiance/foreign
loyalties, etc. for the presidents and vice
presidents who would follow them.
