here is an example of fox news non partisan work:
Rupert Murdoch: Chris Christie Must 'Re-Declare' For Mitt Romney 'Or Take Blame'
Publishing titan Rupert Murdoch sent New Jersey Gov. Chris Christie what appeared to be a warning message on Friday, telling Christie to reaffirm his support for Republican presidential nominee Mitt Romney "or take blame for next four dire years."
The admonition, by way of a tweet from the Murdoch's verified Twitter account, was presumably in reference to the warm relationship Christie, a Republican, showed with President Barack Obama this week, as the two toured New Jersey in the aftermath of Hurricane Sandy.

You're arguing against an assertion that was never made. Nobody ever said that Fox News is unbiased.
The Pew Research Study shows that Fox News is biased and MSNBC is MORE biased. You haven't presented a shred of evidence to prove them wrong.
