I'm not worried either, but I do wonder why they do what they do. I guess the viewership issue could be the answer to this particular poll.
But it seems they do this frequently. What's the point? Do they think they can slant it enough that people will stay home. I don't think that's going to happen because they pretty much lost all credibility with pretty much everyone a long time ago. I think it is more likely to bring out McCain voters, and cause McCain people to work harder, especially in toss up states.
Do they do it so that when they lose they can yell STOLEN!!! RACIST!!! LIARS!!!
