The Corzine campaign is the first I’ve (sort of) covered that had a campaign blog that made sense.
It was written, not ghost-written for the candidate, and done by a person with a name and some experience blogging. It was partisan, and on-message, but in an open way; the guy writing it, Matt Stoller, also had his own voice and was distinct from the campaign press office.
He writes about his experience here:
“First of all, if you’re thinking about blogging for a big campaign or organization, you should do it. It’s going to be unpleasant, you will lose most of the internal battles in the campaign, and you’re going to be second-fiddle to the traditional communications and press operation. But it’s worth it, because the internet is now so big that it simply cannot be ignored. And you my friend cannot ignore the rest of the political world, and seeing politics from the inside makes this oh-so-clear.”
He thinks blogs will hit the bigtime in 2008; I suspect it’ll take a bit longer than that. I also wonder how campaigns will balance hiring people who are readable, and yet who will sacrifice their independence, probably contractually, to the campaign’s demand that everything be on message.
