More Senate retirements

On the heels of Lieberman's announcement, I was surprised to hear that Jim Webb (D-VA) is not running for a second term in the Senate (one of the very few principaled members of Congress and a loss, IMO, though his politics and positions are not always to my exact taste) and that Jon Kyl (R-AZ) is not running again, after 3 terms (not a loss at all, a demogogue and embarrassment, IMO).
