There are two explanations for their seemingly biased reporting: either they had leaks from the Republican side and chose not to release them, or the only leaks they had were on the Democratic side. From the outside, it's hard to know which one is correct. Perhaps what the world needs is multiple WikiLeaks-like organizations that don't have the same editorial slant as Wikileaks? That way leakers can leak their data in several places and it's more likely to be published. (One might even build an anonymous submission tool that makes the submitted data available to all such organizations at the same time.) Of course, if the problem is simply that no one is bothering to attack the RNC, then no amount of additional organizations to publish the data would help. It might, though, lend some credibility to the claim that data isn't being withheld deliberately.
