In this view, polls would only need to be weighted by sample size with a control for house effects, provided that the polls met the theoretical conditions for unbiased sampling — PolitiTweet.org

In theory, a bigger poll/polling average would shrink error until it reached the practical limits of nonsampling error, like undecided voters / turnout / interviewer effect, etc. — PolitiTweet.org

That's definitely not the way things work now, if it ever was. Whether due to low response, noncoverage or opt-in sampling, pollsters don't have unbiased samples. Instead, they do a bunch of increasingly heavy handed statistical adjustments to compensate. — PolitiTweet.org
