Larison doesn’t think either Webb or Warner are good options:
…it shocks me when I read about people seriously contemplating Mark Warner as Obama’s running mate. In the case of Webb, assuming the Democrats win the presidential race, you would be depriving the Senate Democrats of one of their most promising new members and opening up a narrowly won Senate seat to a fresh contest after Gov. Kaine appoints a placeholder for the bulk of Webb’s term. In the case of Warner, this abandons a sure-thing Democratic victory in the election to replace John Warner and throws some poor last-minute replacement into the middle of a campaign he will have a much harder time winning. Unless Obama’s election hinges on Virginia alone, and it’s not clear that this is the state he needs to worry about the most, Mark Warner would do a new Obama administration a lot more good in the Senate as an additional Democratic vote in support of his agenda than he would as a VP nominee who might not even be needed in order to carry Virginia.
