Of course there is, and it's *all* media, not just the US.
The US, more than some other countries, however, has shrugged off any kind of journalistic integrity. Where once the press was the Fourth Estate, used to comment and question the policies of the state on behalf of the people, this is long gone in the US. Instead, the commodification of the media has consolidated editorial power in a very small handful of people, and their political and ideological perspectives overrule the integrity that is, or at least should be, the media. There's no expectation that news is even required to be *factual* anymore; any "news" that isn't based in fact is propaganda, pure and simple.
So yes, there is bias, across the board, and no, this doesn't mean it's generally presented fairly. You need another option in your poll.
