School choice — it's choice! — how can it be bad?

It might be good.

[T]he appeal of school choice cannot be reduced to simple power politics. In fact, the people most resistant to expanding choice are often suburban voters who vote Republican and (sometimes mistakenly) believe their schools are providing quality education. Inner-city minority parents are frequently the most vocal choice proponents because they experience sub-par education firsthand. Republicans who support school choice are actually taking political risks that run counter to raw political calculations.
