His father was a British subject. Therefore Obama was also a British subject making him a dual citizen. A dual citizen owing allegiances to two governments is not a natural born Citizen. Ramaswampy is in the same category. His parents weren’t naturalized Citizens.
With one difference you failed to mention.
Obama’s father never became US citizen.
Vivek’s parents are both naturalized citizens.
Another difference is Vivek is 150 times more intelligent than Obama.
“His father was a British subject. Therefore Obama was also a British subject making him a dual citizen.”
Therefore, the British law that states that persons born to British subjects are also subjects of Great Britain has a direct impact on American constitutional law and who is and who is not a Natural Born Citizen?
