Stocky, blondish Carl J. Friedrich, government professor and expert on public opinion and prrroppagahnda, tried to make practice fit preaching when he managed fellow-teacher Charles R. Cherington's high-powered campaign for election to the school committee inn staid, tradition-bound Concord recently.

Using every trick of the trade, including the bandwagon effect, vague, honeyed generalizations, and half-truths, Professor Friedrich moulded the public opinion of Concord in perfect text-book style. He had them eating out of Cherington's hand.

N.B.: Cherington lost two to one.
