This Jay Mathews article and this Valerie Strauss post both indicate that the Georgetown Day School is the leading contender for the Malia and Sasha Sweepstakes , with the Maret School close behind.
I'm pulling for GDS for one simple reason: it participates in the D.C. voucher program , unlike Maret. And its selection by the Obamas, I believe, will ensure the future livelihood of said program. It's one thing for Candidate Obama to oppose publicly funded vouchers on principle. It's quite another thing for a President Obama to eliminate an existing program and kick his daughters' classmates out of their beloved school. I disagree with Checker on this one: this pick will have major policy ramifications.
