Doug I know I have not posted that often, but do I sound like a moderate liberal?

If net polls are really coming closer to reality than they should be (I'd want more evidence) could it be a matter of sheer size of the sample? That is, once you get into gigantic smaple sizes, does the ratio of rerpesenative to non-representative possible sample change. It has been a long time since my elementary statistic class. I know that you don't gain that much when it comes to truly random samples, but I don't think we ever dealt with how it would affect biased samples. Anyone with the statistical savvy to answer this one?
