I guarantee you by the time attention shifts to Obama again he'll have some better defense and counter-attack for the media narrative prepared (though it will remain to be seen how effective it ends up, I don't see how the extra time can be worse for him).

Look what happened to Bradley Manning, the first public image of him was his chat confession and a huge amount of deeply personal details that really had nothing to do with the leak.
