His Momma was a citizen.
Some want to play birther expert like they did with Obama.
I thought it was a legally-unworkable and below-the-belt maneuver when it was leveled against Obama. Romney thought the same, which is why he stayed away from it. I wonder to what extent the birther movement helped to energize pro-Obama voters, out of a sense that his GOP birther critics were a bunch of scumbags.
