Michelle Obama's Poll Numbers Slide

When Michelle Obama moved into the White House, she instantly became one of the most famous first ladies in history, a symbol of racial pride, a victor in the battle of the sexes and the picture of a modern woman, mother and wife.

But from her days on the campaign trail to her residency in the White House, Obama’s favorability rating has been in flux, from a low of 48 percent in June 2008 to a peak of 72 percent last March to a slide to 61 percent in a recent Gallup Poll.

That 11-point stumble – some might call it a tumble – seems at odds with the focus of a White House publicity team that is carefully crafting her image and building a decidedly current, wholesome, upbeat brand. But while Obama has broadened the reach of her office, White House observers say that the role and projects she has embraced so far are seen by some as disappointingly traditional.
