The Romney family were among a group of Mormons who decided Mexico would be a better place to live than the USA ~ the issue was POLYGAMY!
Just remember, Mexican laws may well suggest that polygamy is prohibited, that that's just for the hidalgos ~ for the Indos, whatever those people want to do is OK. I guess the Mormons thought they'd be left alone. Then they returned!
Maybe Mitt can use this to his advantage even?
