True, it could have been an implication that his parents were able to confer American status upon a Kenyan child. If Barack was not ineligible he was a big fat liar... how long do you think it would take for the questions to get back to him “Oh Barack! I never knew you were born in Kenya! In what village?”
If any Republican were found to have that big a lie in his/her past, do you think he/she would last even through the primaries?
