As Michelle Obama gets ready for her London debut, her popularity is sky high. A fresh Washington Post/ABC News poll shows her favorability at 76 percent, up 28 points since the summer. "Her most striking inroads have come among Republicans who viewed her negatively last year, perhaps in part because of comments she made about feeling proud of her country for the first time," the Washington Post reports. No longer discounted by pundits as a political liability, Republicans now say she looks less "angry." Today, the first lady hits the G-20 summit with broad domestic support on her side.
