I hadn't heard this until Frank Rich told me:
In 1970, Linwood Holton, the state’s first Republican governor since Reconstruction and a Richard Nixon supporter, responded to court-ordered busing by voluntarily placing his own children in largely black Richmond public schools. For this symbolic gesture, he was marginalized by his own party, which was hellbent on pursuing the emergent Strom Thurmond-patented Southern strategy of exploiting white racism for political gain. After Mr. Holton, Virginia restored to office the previous governor, Mills Godwin, a champion of the state’s ‘massive resistance’ to desegregation.
Today Anne Holton, the young daughter sent by her father to a black school in Richmond, is the first lady of Virginia, the wife of the Democratic governor, Tim Kaine. Mr. Kaine’s early endorsement of Mr. Obama was a potent factor in his remarkable 28-point landslide on Tuesday.
