How does President Polk compare to Obama. Seems Obama must match equally to Polk in order for Obama to be a natural born citizen.
Polk had two US citizen parents. Obama does not.
The Constitution is clear. Obama was born in the United States so he is a natural born citizen. Naturalized citizens are those born outside the United States but later receive legal citizenship.
There are several ways to be deemed a natural born citizen, my friend. All our not equal.
