I'm sort of late to this story, but one thing struck me about the John Edwards blogger brouhaha. After Edwards appeared ready to fire bloggers whose writing had become a point of controversy, other bloggers threatened to oppose Edwards in the primary. Then when he relented, they celebrated it as a crucial moment for the legitimacy of bloggers in mainstream politics.
But will this open doors to bloggers being hired by campaigns? My guess is, just the opposite. What this episode demonstrated is that, if you're a candidate, hiring a blogger may or may not win you the loyalty of that blogger's friends. But firing that blogger will certainly bring their wrath down upon you. But campaigns, of course, fire staffers pretty often. So why would you hire somebody you can't fire?
