Can we expect the US 2016 polls to be any good?
The American polling community is no stranger to controversy during hard-fought election campaigns, pollsters often have serious arguments about appropriate methods (such as whether random-digit dialing or using voter registration lists are better for primary elections, and what is the proper percentage of mobile phone numbers in a sample). Politicians certainly argue with pollsters when they are not happy with poll results, often citing the shopworn phrase “The only poll that counts is the one on election day.”
