The old-fashioned way of getting political intelligence was through inside sources, who often told inside stories to build their own credibility with journalists and other politicos.
Now there's a hypothesis that online media could inadvertently reveal campaign secrets. An article in Politico notes that a surge in last-minute edits to Wikipedia entries in 2008 forecast the vice presidential selections of Sarah Palin and Joe Biden. Interesting. We now can test this hypothesis in the runup to Romney's selection. Watch that space.
