Steve Benen points out that the American people are just that into her:
A Washington Post-ABC News survey conducted over the past few days shows a dramatic turnaround: Her favorability ratings are at 76 percent, up 28 points since summer. The number of people who view her negatively has plummeted. 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.
This is in a story that quotes far more Republicans than Democrats. The numbers speak for themselves. Michelle Obama just isn't the political vulnerability that many conservatives thought she was, probably because the American people as a whole don't share certain individual hang-ups common to conservative media figures
