Mark Warner Bows Out Of Presidential Run

Thing that make you go, hmmmm. Former Virginia Governor Mark Warner, seen as the one great hope for Democratic Moderates (remember them?) in the race for president in '08 has decided not to run. The first question that comes to mind is why so early? Usually candidates wait until after midterm elections before they even acknowledge they're thinking about running. The second question is what's going on behind the scenes? He says he wants "a real life." If so, why did he go into politics in the first place? Something's not right here.
