Back in the Brown vs. Board days, in the death throes of the Harry Byrd Democratic machine, the state of Virginia adopted a policy called "Massive Resistance" to integration. Prince Edward County went so far as to close their entire public school system for five years, from 1959 to 1964, rather than allow black children to attend.
Barack Obama was three years old when those schools re-opened.
