“Polling may need a shot in the arm, but it certainly does not rate a shot in the back. The snipers on all sides are having a field day.” (from In Defense of Public Opinion Polling by Kenneth F. Warren)

These are the sort of words that could have been said in the offices of UK polling companies over the last few weeks. The fact that they were actually said by pioneering US pollster Archibald M. Crossley in 1949 only proves that the challenges pollsters face today aren’t new.
