Nate Silver examined the claim (put forward by Rassmussen, among others) that the filter they used for 'likely voters' (essentially, overweighting in their polls the preferences of those who expressed a stronger desire to vote...) was what resulted in their polls' results skewing away from the actual results of the election... but Silver claimed that his statistical analysis showed that that was not what skewed the polls' results. So, if that is ruled out as the cause, we are left with various problems with their sampling techniques (not calling cell phones, taking the first person who answers the phone instead of randomly selecting the respondent to use, using recordings instead of actual humans to ask the questions - resulting in much lower response rates, etc., etc.)
