I assure you, I'd be ignoring polls no matter what the score was. It has nothing to do with my viewpoint other than that I think that polling is a completely useless activity. That applies to psych and sociology polling methods as much as it does to politics. It has been a long held viewpoint -- it is hardly dependent upon my support for Sanders.
I also think that demographic polling by news organizations (and others) to increase their popularity and pander to a population segment is the number one thing wrong with our press nowadays.
Statistics in general I have no problem with, but opinion polling tends to be useless due to the limitation of options and the fact that people don't really have a tendency to know what they want until they see it. Furthermore, there are always some major problems in methodology when you are trying to evaluate people in general. If it were otherwise, personality surveys/categories would actually make sense (which they don't). It usually boils down to a matter of measuring the wrong thing.
In the area of political polling, the problems that crop up are:
1) They throw out results based on flawed assumptions.
2) Every single moment in time is a point at which someone can change their mind.
3) The polls themselves can be used to affect the political process via self-fulfilling prophecy.
So why is it that polling has been so accurate?
Are Democratic primary polls accurate? In individual states they are good, with a few exceptions. At an aggregated level, they are remarkably accurate. The delegate-weighted polling margin has a total error of 3.1%. This is better accuracy than one would expect from the reputation of polling these days. The overall error is also not nearly enough to change my calculation from yesterday.
Above are Election Day results so far this season, plotted against poll medians taken shortly before the election. The correlation coefficient is +0.85, pretty good. Red symbols indicate caucus states.
