Vilsack's communications director Matt Paul, who worked three or four hundred levels above me on the Howard Dean campaign in Iowa, has joined the Blouin campaign. Hotline says he is going to "run" the campaign, so I assume that means he'll be acting as campaign manager. While the Dean thing doesn't exactly bode well for Blouin, Paul can't really be blamed for the mistakes of Jeannie Murray.
Update: He is indeed campaign manager. Also, I don't think it's correct to view this as another example of Vilsack showing support for Blouin, since it was Blouin who introduced Paul to Vilsack in the first place.
Update 2: Chris also sees this as implicit Vilsack support, saying Vilsack wouldn't let a staffer work on a campaign he didn't like. Seeing as how Vilsack pretty plainly supported Kerry while Paul worked on the Dean campaign, I have to disagree with his assessment.
