I think the lastest MoveOn ad featuring former US Marine Lee Buttrill is superb in terms of content and effectiveness. But I'm somewhat concerned about the way the ad skirts the campaign finance laws. As I understand it — and I'm in no way an expert — the ads can't endorse a candidate, although they can talk about them.
If that's the rule, this ad comes very close to the line. Rather than say “Vote for Kerry” the ad no doubt accurately indentifies the speaker as “Voting for Kerry”.
If the statement is accurate, it's just descriptive. So perhaps technically it's not an endorsement and thus within the letter of the law, maybe brilliantly so. But it can't be consistent with the spirit of the campaign finance rules.
PS. There are a lot of good runner-ups on the MoveOn page, although I'm especially partial to Kenneth Berg
