In Boston, Jeff Jacoby notices in the battle for school choice our gubenatorial candidate Anthony Williams is a leader.

As it happens, the ADL regional board isn’t the only liberal voice in Philadelphia calling for expanded school choice. State Senator Anthony Williams, a black Democrat and a candidate in Pennsylvania’s gubernatorial primary this week, is the founder of a charter school, a champion of vouchers, and an ardent believer in the power of competition to improve the quality of education. His position puts him sharply at odds with the state’s largest teachers’ union, which opposes choice and has endorsed his main opponent. But Williams — like the local ADL leadership — sees school choice as the great civil rights battle of the day.

“Anybody who was for Brown v. Board of Education — it baffles me that they would be against vouchers,’’ he told me last week. “Brown condemned schools that were separate and unequal. Well, that’s exactly what we’re back to now — schools that are segregated by income, by ZIP code, by race.’’
