Steve Sisson Turns On A Light

I've been trying to get a handle on how I see the current Democratic Party primary for weeks now, and have had no success putting it in words on paper (OK, screen).

Tonight, Steve Sisson managed to nail it;

It's ironic how many Virginia Democrats and their left-leaning blogs are supporting Jim Webb in the primary because he voted for George W. Bush in 2000 and endorsed Allen's Senate campaign in 2000.

Can someone explain to me why the left is so obsessed with a man who once wore the uniform, but now denounces the mission of his fellow soldier in arms?
