Yeah, they just had to get that in there, didn't they? At least they gave her credit for growing up and going on to bigger and better things.
Of course, but it illustrates the biggest difference between the two families: the Bushes are human: they laugh, they cry, they screw up and most importantly, they have the ability to laugh at themselves. The girls avoided the spotlight as much as they could throughout their father's career. Laura stayed out of governmental affairs.
Obama has no sense of humor, only a biting, condescending sarcasm (e.g. Nancy Reagan and speaking to the dead). Michelle is perpetually angry and totally joyless, except in the satisfaction of besting others. The girls will be paraded out as props, as they have been during the campaign. And neither of the Obamas will tolerate being mocked.
It's going to be a depressing four years in many more areas than the economy.
