Mitt Romney’s father was a Mexican citizen therefore Mitt Romney is not a naturalized citizen and can not hold the office of president. If Obama’s daddy is a Kenyan then he is not a naturalized citizen either, so neither legally can hold the office of president.
What is good for one is good for all.
George Romney was born in Mexico but he was never a Mexican citizen, any more than Juan McCain was ever a citizen of Panama. George Romney even ran for President of the United States—I don’t recall anyone saying he wasn’t eligible.
