In August 1963, the month of the March on Washington at which Martin Luther King gave his “I have a dream” speech, 50 percent said the country was moving “too fast” on integration, versus 10 percent who said “not fast enough”—a ratio of 5 to 1. That ratio fell to 2 to 1 (30 to 15 percent) in January, during the debate over the Civil Rights Act. But in October, on the eve of the election, it was back over 3 to 1 (57 to 18 percent) again. It never disappeared.
