Yes, he is.
And any argument to the contrary is just racist in nature.
See what I did there?
Two can play that silly ass game.
Just took a quick look at the Constitution, and yep, you’re right!
"The Constitution does not in words say who shall be natural-born citizens. Resort must be had elsewhere to ascertain that. At common law, with the nomenclature of which the framers of the Constitution were familiar, it was never doubted that all children born in a country of parents who were its citizens became themselves, upon their birth, citizens also. These were natives or natural-born citizens, as distinguished from aliens or foreigners. Some authorities go further and include as citizens children born within the jurisdiction without reference to the citizenship of their parents."
"In Minor v. Happersett, 21 Wall. 162, this court held that the word 'citizen' is often used to convey the idea of membership in a nation, and, in that sense, women, if born of citizen parents within the jurisdiction of the United States, have always been considered citizens of the United States, as much so before the adoption of the fourteenth amendment of the constitution as since; but that the right of suffrage was not necessarily one of the privileges or immunities of citizenship before the adoption of the fourteenth amendment, and that amendment did not add to these privileges and immunities. Hence, that a provision in a state constitution which confined the right of voting to male citizens of the United States was no violation of the federal constitution."
