Huh? His comment was critical of Howard Dean's campaign.

Here's what he said: "No organization like Wikileaks can survive a cult of personality, or one person’s delusions of grandeur. Trust me — I worked on Howard Dean’s presidential campaign."

He's not saying "Trust me, I worked on a political campaign." He's saying, with a bit of dark humor, "Trust me, I know what it's like to be involved in a cult of personality and watch it fail because of it."

No, that he's boasting about it as evidence of why he should be trusted over Assange.
