Oh man you’re right I’d forgotten that.

I don’t think superdelegates are to prevent popular candidates (see Obama), I think they’re to get a comprehensible slate of candidates to focus on issues and themes and not on turning the Iowa caucus into something bizarre by claiming to be a Democrat who just happens to demand we all live in the sea or something.

Again, republicans don’t have this problem, and they’re well known to fund ‘spoiler candidates’ with the intention of wrecking momentum or message or other campaign aspects.
