I don't think a "balanced" news network exists.
Remember, someone owns that station and it's usually a corporation. If you want to know a company's true political slant, look at the corporation they are owned by. In Houston everything is owned by Clear Channel, which is a conservative corp.
I'm not sure how people can say that ABC is liberal when it's owned by disney! LOL I think they blanket any agency that's not fox with the "liberal" label.
