"Have you no sense of decency, sir?" asked attorney Robert Welch in a climactic moment in the 1954 Senate hearings that pitted Joseph R. McCarthy against the United States Army, President Dwight Eisenhower, and the rest of the political establishment.

With a journalist's eye for revealing detail, Robert Shogan traces the phenomenon and analyzes television's impact on government. Despite McCarthy's fall, Mr. Shogan points out, the hearings left a major item of unfinished business-the issue of McCarthyism, the strategy based on fear, smear, and guilt by association.
