Is Jim Webb maneuvering to get Obama's VP nod?

Virginia Senator Jim Webb sure seems to be maneuvering to be picked as Barack Obama's vice-presidential running mate:

• The cover story in today's Parade Magazine is an excerpt from Webb's latest book, A Time To Fight: Reclaiming a Fair and Just America. Judging from the excerpts and reviews, this is a classic — and remarkably well-timed — example of a political statement, of the sort written with an upcoming campaign in mind.
• This past Friday, Webb plugged his book on National Public Radio's All Things Considered. He's scheduled for more interviews on Letterman and elsewhere next week.

Webb would clearly bring some strengths to the Democratic ticket:

• In some respects, Webb is a younger version of John McCain.  He served heroically in Vietnam, was badly wounded in combat, and was medically retired from the Marine Corps as a result. There's little room for doubt that many conservative- to moderate independents would view him favorably.
• Webb has a track record of acting as a political independent, sometimes pugnaciously so. He resigned from his position as Ronald Reagan's Secretary of the Navy because of policy disagreements.  In Virginia's 2006 election he switched parties; beating long odds, he captured the Democratic senatorial nomination and went on to unseat long-time GOP incumbent George Allen. At a White House welcoming reception, Webb minced no words with President Bush (to the point of being insulting if you ask me); say what you will about Webb's manners, this year seems to be one in which his kind of blunt, maverick independence might be appealing to some of the electorate.
• Webb's home state of Virginia has long been reliably Republican in presidential elections, but some polls suggest that this year its 13 Electoral College delegates could be up for grabs. The opportunity to put a popular Virginian on the ticket would certainly be of interest to the Democrats.

I'd love to know what's been going on behind the scenes, and how much (if at all) the Obama camp has been involved in Webb's conveniently-timed book promotions.
