The former Democratic senator from Nebraska, Bob Kerrey, understands why the John Kerry-endorsed Ned Lamont must be defeated. He is campaigning with Joe Lieberman today in Connecticut. Kerrey is a member of “Dems for Joe,” a band of Democrats who haven’t bailed on Joe. The group includes former Sens. David Boren (OK), John Breaux (LA), Bryan (NV), DeConcini (AZ), and Johnston (LA).
