Senator Jim Webb (D-VA) has taken himself out of contention as a running mate for Barack Obama. This makes him the second major contender (the other being Ohio Governor Strickland) to rule out running on the 2008 national ticket.
I find it kind of interesting that we have people ruling themselves out like this given that everyone seems to consider Obama a shoo-in for November. Taking the #2 spot would thus be a free ride to the Vice Presidency and would put you as the front runner in 2016 (assuming Obama serves 2 terms).
Of course there could be sincere personal reasons for both men not wanting to run but it does make you wonder if perhaps there is something going on behind the scenes
