Of the major outlets only Fox News has a clearly partisan bent. There are many ideological rags (Reason is Libertarian, Jacobin is Socialist, etc.) But the majority of major news sources are non-partisan and non-ideological to the point of giving undue weight to completely foolishness just because the foolishness benefits a certain party. They have systemic biases, owing to being staffed largely by elite educated urbanites with close proximity to power. That's different from being partisan. Where parties are concerned this bias tends to cut against them both in different ways.
