The Mittwit was born in Detroit. Unfortunately, that means he's eligible, even if his momma had stepped off the plane from Leningrad, Mitt having been conceived along the shores of Lake Baikal. The actual citizenship status of George and Lenore is immaterial.
Absolutely not true. If Mitt had been an American Indian born in Detroit in 1920, he would NOT be even a citizen, let alone a "natural born citizen." Place of birth is but one requirement to be a "natural citizen." Anchor babies are NOT "natural citizens."
