What media are you talking about? In the US we have basically to flavors of media, the right wing media and the mainstream media. Now, because media organizations are driven by profits, they tend to favor sensationalism and that does generally favor the right wing. But if you pay attention, credible sources will report all of the truth. Case in point, was the swift boating of John Kerry. All the data was reported in credible news agencies like CNN; however that didn't stop CNN from sensationalizing everything else and dragging it out giving the appearance there was some there, there, when in fact there wasn't. Journalism and media institutions, with few exceptions, e.g. Fox News, change over time. CNN has changed. It's much less forgiving of Republican propaganda than it once was, though it still has a penchant for sensationalism. And as long as we have a free and independent press that will always be the case. Do you want a state controlled press a la Putin or a free press? I'll take the free press every day.
