This seems to be the crux of it. No, what I am saying is that when you want to laugh at the polls/pollsters, you should be arguing how their methodology was wrong and what they could have done to find the true proportion +/- some standard error with however much confidence level. Simply laughing at pollsters when the minority wins is not good enough. 20% chance of winning and then actually winning does not seem all too unlikely to any reasonable person.
