This might be a grudge between him and Laura. Let me explain.
It was Laura Bush's secretary that announced that the Blair House would not be available until the normal day of the 15th. It was Laura that gave them a zinger. Obanana might be giving a childish retaliation.
Didn’t Chelsea attend the same school as the Obama girls? Not to give any credit to Hill & Bill, but I don’t remember them trying to move in the Blair House early so Chelsea could start school. Just as Laura’s secretary said, Jan 15 is the traditional date that all the presidents stuck by. Seems like Michelle expects catering to her every whim. It’s only a matter of time before she embaresses us all again.
