No, I wasn't being sarcastic. I don't know what polls you are talking about, or maybe you're just using hyperbole to try and get your point across. Probably the most well known poll, at least around here, is the Gallup poll. You can see the historic record of their presidential polls by going here:
http://www.gallup.com/poll/9442/election-polls-accuracy-record-presidential-elections.aspxAs you may notice, they were only wrong once since 1936 and are generally within a percent or two in accuracy. They did not show democrats leading in every race for the last 40+ years.
I agree, there are lots of polls, and lots of them are not unbiased, scientific polls. Those are the ones you may be describing.
I agree, too, the the media is extremely biased and often reports the polls they feel push their agenda.
My point was that if you poll a large, randomly selected population about how they intend to vote, using carefully designed questions and scientific methods, it will reflect the actual voting rather well, regardless of the number of voters who actually go to the polls.
