Winston Churchill’s mom was American and His father was British. He was not born in the US.
So if 0 was born in Kenya does that mean that Churchill was a natural born American too? Could Churchill have run for the US Presidency?
I would not consider Churchill or Obama as Natural Born Citizens of the USA, under Article I Section 1 even if they were born in the USA. Citizens yes - Natural Born pertaining to constitutional eligibility for president-no.
