Headline at the Politico Web site before the news conference by John and Elizabeth Edwards:
Edwards to Suspend Campaign
Headline at CNN.com after the Edwards' news conference:
Edwards: 'Campaign goes on' despite wife's cancer
The upshot: Sometimes it's better not to rely on an anonymous source, as Politico did. And don't link to a lone story with a lone anonymous source as Drudge did. Just wait for the news to happen. At least Wonkette has the courage and humor to admit that it didn't know what was going on.
UPDATE: Politico's blogger apologizes.
