I don't see the need to put Webb on the ticket -- although he could name him as Secretary of Defense. The environment of temporarily-reduced violence that the surge created (and gave McCain the nomination) is collapsing, and the case against the war will be easy to make. If he needed to shore up his foreign policy bonafides, he could simply pre-announce his foreign policy team (SecState Biden, bring Perry back as SecDef, etc.); putting realist foreign-policy "veterans" back in the White House would add a lot to the narrative of "un-doing" the damage Bush has done.
As for the list, it excludes Brian Schweitzer, the Democratic MT Gov. who's a strong supporter of the second amendment and a major opponent of REAL ID and the Patriot Act. The Gov. has said in speeches that REAL ID is the first step on the road to a police state.
I think that the Dem's path to victory is in the Mountain West, where they have made the most gains in the past 4 years, hence their choice to have the convention in Denver. That's why I think it'll be a western Gov., either Schweitzer, Richardson, or the Governor here in Colorado, Bill Ritter. Ritter is a pro-life progressive (he was even a Catholic missionary in Zambia in the late 80s) from a swing state (that was red until '06) who's decent on gun rights.
