I think Michelle Rhee's daughters go to a DC public school. Surely the Obamas cannot be expected to throw their daughters into a poor academic environment (or, infinitely worse, a dangerous environment), but if there's a school good enough for the Chancellor's daughters, might that school also be worth considering? Imagine the message of support it would send to teachers, parents, and students in the DC public schools!
Sadly, this probably isn't an option. Real life isn't the West Wing, and there are too many risks and variables associated with gambling on a public school.
What a commentary on the sorry state of American education.
PS -- thanks to Amy for the correction re: number of Rhee's daughters.
