British public opinion polling organizations enjoyed a varying but generally considerable degree of success in predicting the outcome of the British general election of 1950. This success is all the more striking in view of the extremely close balance between the Labour and Conservative parties. Liberal candidacies in 475 of the 625 constituencies also posed a formidable predictive problem. Professor Eldersveld here reviews the record and methodology of the British polls during the 1950 election and offers an interpretation of the meaning and implications of this election for British politics.
