" To everything, in other words, there is a season, and McCarthy’s hubris hastened the end of his hour upon the stage. “I was fully aware of McCarthy’s faults, which were neither few nor minor,” Cohn recalled. “He was impatient, overly aggressive, overly dramatic. He acted on impulse. He tended to sensationalize the evidence he had—in order to draw attention to the rock-bottom seriousness of the situation. He would neglect to do important homework and consequently would, on occasion, make challengeable statements.” The urge to overstate, to overdramatize, to dominate the news, could be costly, and so it proved to be for McCarthy. The Wisconsin senator, Cohn said, was essentially a salesman. “He was selling the story of America’s peril,” Cohn recalled. “He knew that he could never hope to convince anybody by delivering a dry, general-accounting-office type of presentation. In consequence, he stepped up circumstances a notch or two”—and in so doing he opened himself to attacks that proved fatal. He oversold, and the customers—the public—tired of the pitch, and the pitchman. "
