Back-to-school at Sidwell Academy could get pretty awkward. Among the parents at the Obama girls' new school is Hillary’s poll guru Mark Penn. Other Clintonite classmates include the children of Mandy Grunwald and Capricia Marshall. And Obama could also face a grilling from new Meet the Press host David Gregory, whose kids also study at the school. Clintonista-turned-Obamaite Patti Sollis Doyle insists, however, that politics are checked at its school gate. "It's a great school, and my kids have just really grown and thrived at the school. But what's great about it is that, sure, there are a lot of quote-unquote D.C. power parents, but in the carpool and at back-to-school night, they're just regular parents."
