I thought that former Virginia governor Mark Warner would be the Democratic presidential nominee in 2008. But evidently, he's backing out of the race.
The reason for believing that Warner would take the Dem banner was simple: Democrats win the White House when they nominate Southern governors who are perceived-moderates. They did it in 1976 with Jimmy Carter and again in 1992 with Bill Clinton.
Warner's withdrawal means that now no Virginian will vie for the presidency in two years. George Allen, the state's junior Senator, a conservative Republican, self-destructed as a viable candidate during his bid for re-election to the upper chamber this year. (It appears that he will nonetheless win the Senate race in four weeks.)
