The best news for straight info is public television, McNeill/Lehrer, and the interview shows they have like Charlie Rose. Not nearly as many ads either.
Visit the C-Spans, too. Their scheduling, because it's often done on the fly, is very unpredictable but they do have some really good stuff fairly often. You can get whole hearings, think tank seminars, book reviews and author interviews, etc. No ads either.
CNN is OK most of the time, some of the shows. For basic news, Arron Brown does an OK summary of the day's big events. I like some of Lou Dobbs' shows but the ads get real old real quick. He sometimes has some interesting topics and guests but they never get to get into deep enough. Not enough time. For twenty minutes of news you have to watch ten minutes of ads. At least it seems that way.
Fox is not news but a 24 hour right wing editorial. Unfortunately, they sell their bullshit to a lot of folks without giving the full story. I've watched them report on senate hearings where I watched the whole thing on C-Span, then heard their reporting of it. You wouldn't know it was the same event. I not only think that sucks but I also think they are lacking in the morality that they so like to claim exclusive rights to. Twisting a story to an agenda, but selling it as a fully balanced news report instead of an editorial, is a slam on the journalism profession and I feel it is morally wrong. It's twisted, edited reporting, delivered in a venomous style, with smugness, and hate speech. And twenty-four hours of that shit, even if they admitted what it was, is too much. The way they deliver it, it's easy to see how folks who don't know better buy into their crap. They've been sold a bill of goods and don't even know it because they never took the time to learn the whole story. Unfortunately, some of them buy it hook, line, and sinker, and then vote accordingly.
If that's all I knew about some of the topics, I'd probably vote that way too.
