Paul Rosenberg still wants John Edwards on the ticket, citing new opinion polls that show he helps Barack Obama more than many other possible running-mates.

Virginia Senator Jim Webb seems to have taken himself out of the running by co-sponsoring a bill to allow offshore oil drilling in Virginia.

Wisconsin Senator Russ Feingold seems to have taken himself out of the running by criticizing Obama for opting out of public financing for his general-election campaign.

General James Jones has to be off the list after he accompanied John McCain to a campaign event in Missouri.

As I’ve written before, Obama must above all do no harm with his VP choice. That means he can’t choose anyone who would alienate the Democratic constituencies that favored Hillary Clinton in the primaries. If I were in his position, I would probably choose someone close to the Clintons, like Wes Clark.

However, if Obama doesn’t want to tap someone from the Clinton circle, a number of other choices, including Joe Biden, Bill Richardson and John Edwards, would be ok by me.

If he wants an “old wise man,” I much prefer former Florida Senator Bob Graham to someone like former Georgia Senator Sam Nunn.

I am absolutely, implacably opposed to putting any Republican (such as Nebraska Senator Chuck Hagel) on the Democratic ticket. The next president is going to appoint several Supreme Court judges, and I don’t want any conservative to have any chance of becoming president.

Make the case for the running mate of your choice in the comments.

UPDATE: Good discussion about the pros and cons of Biden on the ticket in the comment thread under this diary: Biden Drank Graham’s Milkshake: Veep Audition?
