Because of his support/endorsement of McCain. The Dems made a rule (because of Zell Miller and his endorsement of Bush in 04) that any democrat crossing the lines to endorse a republican (or presumably 3rd party too) candidate would be stripped of their superdelegate status. So that will be one less superdelegate for CT. Can’t say I necessarily disagree with this. Would kinda be embarrassing for one of your delegates to vote for someone in another party at the convention.
(HT FDL)
Can’t argue with it. I’d only say they ought to go further and get rid of all super-delegates.
