There was a post on here maybe a few months ago (couldn't find it right now) about how a certain percentage of people will just answer polls randomly/adversarially/jokingly, and I think the number they gave was something like 7% (I think they ran a poll with one nonsense answer and 7% of people picked it, something like that). Anyway that was just one data point, and I'm sure there are cross-cultural differences, but I think the idea still stands that there is an absolute margin of error in polling that is independent of the true percentage and sample size.
