Via Gallup:
Gallup asked those who perceive political bias in the news media to say which party the news media favors. Almost two-thirds (64%) of those who believe the media favors a political party say it is the Democratic Party. Only about a third as many (22%) believe the media favors Republicans.
This is not new. Americans who perceive media bias have always said the direction of that bias leaned in favor of the Democrats, although the percentage holding that view has varied. The gap was smaller in 2003 and 1995, but was more similar to today’s attitudes in 2000.
