Over on DailyKos the reaction to this was somewhat skeptical since Kerrey and Lieberman are apparently very tight (nice how he forgets to mention the relationship between Kerrey and Sen. Webb). However he does note that current Senator Ben Nelson (D-NE) is far to the right of anyone else in the Democratic caucus, without bashing Dems on national television on a weekly basis like Lieberman does.
That's a shame because he's really funny, bright..
maybe someone can get him to see the light and come over to the Progressive/Populist side on these.
