You don't know what a journalist is. It is actually requires reporting real news, not forging documents to influence elections. You are ignorant.
What Julian Assange has been accused of doing, what he admits to doing, is publishing leaked information rather than forging it. That's kind of one of the things journalists do.
As for influencing elections writers working for the Jeff Bezos Propaganda Blog (also known as the Washington Post) and the Carlos Slim/Ochs Sulzberger Propaganda Blog (also know as the New York Times) have written articles openly admitting that they're biasing their coverage of this election in the hope of influencing it, something that should be obvious to anyone who reads the political coverage on those blogs.
You're floundering around to find a definition of 'journalist' that doesn't simply say "people who work for media outlets I like (e.g. the Jeff Bezos Propaganda Blog, the Clinton News Network etc) =journalists, people who work for media outlets I don't like (e.g. Wikileaks, perhaps Fox News and Breitbart as well)= not journalists.
