Sasha and Malia's Grandmothers

NBC news is covering the candidates' "Family Ties," and recently zoned in on Barack Obama's relationship with his mother, Ann Dunham, who died of ovarian cancer ten years ago. That means the girls never even met their grandmother on their Dad's side. Meanwhile, they're spending a lot of time with their other grandmother, Marion Robinson, who quit her job at a bank to help take care of Malia and Sasha during the campaign.
