A new article is on the way, but meanwhile I was struck by this photo of President Obama and Michelle for obvious reasons. (you can view the original on the White House site at http://www.whitehouse.gov/photogallery/In-Europe/)
A political colleague of mine and I recently had a discussion as to whether or not President Obama is vulnerable to the temptations of the many women available to him. My (male) colleague pointed out to me that our president has the look of a man who is getting everything he needs at home. This photo suggests interesting possibilities in that area.
Of course, the specific framing of the photograph probably says more about the photographer's leanings than it does about the Obamas.
(And by the way, this speculation is purely in respectful and good fun and in no way implies any insider information on the relationship of the First Couple!)
