Valerie Jarrett, White House advisor, talks  about the benefits of children in the White House:
JARRETT: You know, we can be in a very serious meeting in the Oval Office, and out of nowhere, here comes Michelle with Malia and Sasha right behind, and you could be talking about the most serious thing in the world, and they have the ability to break the tension and come in and provide joy and laughter and youth and spirit and energy, and I think all of that's good for our country.
Now I suspect that Jarrett doesn't really think it's a good idea that the First Family bursts into the middle of meetings with all that joy and laughter and youth and spirit and energy. But I guess she thinks we, the electorate and the body politic must think it's a good idea. Not sure which interpretation is more depressing.
