President Barack Obama's wife choked up as she addressed girls at the Elizabeth Garrett Anderson School in Islington, north London, where her visit brought screams of excitement.

In my opinion this little clip gives us yet another example of what a transformational couple the Obamas have become in the world. In what could easily have been contrived for the cameras, the sense is that something genuine and real is happening, not faked. And as seen in this clip, Michelle Obama's message is especially resonant with young women and girls of color.

Earlier this week Gallup released their Favorable numbers for both the President and First Lady and for the first time she has scored higher than her husband. While this isn't unusual for most wives of Presidents, it does represent a milestone of sorts for Michelle Obama. Barely a year ago talking heads were bleating about her being a liability to her husband's campaign, that her outspokenness was a distraction in the middle of grueling primaries. And just a year ago the famous line,

"For the first time in my adult life, I am really proud of my country because it feels like hope is finally making a comeback"

...made headlines, twisted all out of shape into something sinister and decidedly un-American by a compliant press. Painted as "the angry black woman" her disapproval numbers shot up.

Now, however, with 72% of Americans having a favorable opinion and only 17% an unfavorable one she is likely the most highly regarded woman in America. Or at least up there with Oprah. Perhaps most surprising is that more Republicans now have a favorable opinion of Michelle Obama than unfavorable. The same cannot be said for her husband.

It is quite likely Michelle Obama will become the most admired woman in the world soon, if she isn't already. That is good for the Obama's but, after the last eight years, is a great thing for the United States.
