I've blogged in the past about the occasions I found myself being waved at in a very personal way by both Bill Clinton and H.M. The Queen. Michelle Obama turned up to visit the secondary school round the corner from the office just now. A crowd of people gathered from Chapel Market. This is not a section of the public best known for its interest in the Special Relationship. All they wanted to do was catch a glimpse. But when the motorcade of identical black vehicles drew up their windows were all blacked-out, meaning not only did people not see anything, they couldn't even tell that they were waving at the right vehicle. People moved away with a peculiarly flat feeling.
If Her Maj can make herself visible to all the citizenry, gunmen and all, I don't see why the wife of the President can't do the same. After all, as Mick Jagger says, all you've got to do is give them a glimmer.
