I don't think the national cable news media and major print media are as liberal as you guys think -- they're just not aggressively anti-liberal, and thats probably whats bothering you.
For what its worth, here's a link to a story from Feb 27 of last year that refers to John Kerry as "trolling for votes" in Florida. Thats unflattering language, to say the least.
