You are mistaken, many of we ‘Birthers’ believe having a Kenyan father immediately removes the natural born citizen status. Apparently, Senators also agree, including Barry Soetoro, since they signed onto a non-binding resolution in April of 2008 which stated that to be natural born, McCain had to have two American citizen parents. Disinformation is the easiest to spread when you’re among ignorant folk.
Mistaken about what? My brother in law is English, as in born in London. My sister is of course a natural born citizen. They have two children, both of whom were born in Chicago. Are those children eligible to run for POTUS? If they are, your point is wrong.
