There are many books that document the liberal media double-standard, in examples of the hard numbers of stories done (such as the number of stories done of rising feul prices when Bush was president in 2008 vs. now under Obama, or the fully proven Anthony Weiner scandal vs. the never proven Herman Cain allegations. Both gave more than double the stories when it damaged Republicans, even devoid of evidence)

Even polls of reporters, of how they vote, and how they view the issues (as compared to the majority of Americans) reveals from their own mouths the blatant and unquestionable liberal bias in reporting.
