Back in the Dark Ages of 2004, when YouTube (and HuffPost, for that matter) didn’t exist, a campaign could tell a brazen lie, and the media might call them on it. But if they kept repeating the lie again and again and again, the media would eventually let it go (see the Swiftboating of John Kerry). Traditional media like moving on to the next shiny thing. But bloggers love revisiting a story. So when Palin kept repeating her bridge to nowhere lie, bloggers kept calling her on it. Andrew Sullivan, for one, has made a cottage industry of calling Palin on her lies. And eventually, the truth filtered up and cost McCain credibility with his true base: journalists.
The Internet may make it easier to disseminate character smears, but it also makes it much less likely that these smears will stick.
