Howard Zinn writes in _A People's History of the United States_ (NY: HarperPerennial, 1980):
***** The publicity given to the student protests created the impression that the opposition to the war came mostly from middle-class intellectuals. When some construction workers in New York attacked student demonstrators, the news was played up in the national media. However, a number of elections in American cities, including those where mostly blue-collar workers lived, showed that antiwar sentiment was strong in the working classes. For instance, in Dearborn, Michigan, an automobile manufacturing town, a poll as early as 1967 showed 41 percent of the population favored withdrawal from the Vietnam war. In 1970, in two counties in California where petitioners placed the issue on the ballot -- San Francisco County and Marin County -- referenda asking withdrawal of the U.S. forces from Vietnam received a majority vote.
In late 1970, when a Gallup poll presented the statement: "The United States should withdraw all troops from Vietnam by the end of next year," 65 percent of those questioned said, "Yes." In Madison, Wisconsin, in the spring of 1971, a resolution calling for an immediate withdrawal of U.S. forces from Southeast Asia won by 31,000 to 16,000 (in 1968 such a resolution had lost).
But the most surprising data were in a survey made by the University of Michigan. This showed that, throughout the Vietnam war, Americans with only a grade school education were much stronger for withdrawal from the war than Americans with a college education. In June 1966, of people with a college education, 27 percent were for immediate withdrawal from Vietnam; of people with only a grade school education, 41 percent were for immediate withdrawal. By September 1970, both groups were more antiwar: 47 percent of the college-educated were for withdrawal, and 61 percent of grade school graduates.
There is more evidence of the same kind. In an article in the _American Sociological Review_ (June 1968), Richard F. Hamilton found in his survey of public opinion: "Preferences for 'tough' policy alternatives are most frequent among the following groups, the highly educated, high status occupations, those with high incomes, younger persons, and those paying much attention to newspapers and magazines." And a political scientist, Harlan Hahn, doing a study of various city referenda on Vietnam, found support for withdrawal from Vietnam highest in groups of lower socioeconomic status. He also found that the regular polls, based on samplings, underestimated the opposition to the war among lower-class people.
All this was part of a general change in the entire population of the country. In August of 1965, 61 percent of the population thought the American involvement in Vietnam was not wrong. By May of 1971 it was exactly reversed; 61 percent thought our involvement _was_ wrong. Bruce Andrews, a Harvard student of public opinion, found that the people most opposed to the war were people over fifty, blacks, and women. He also noted that a study in the spring of 1964, when Vietnam was a minor issue in the newspapers, showed that 53 percent of college-educated people were willing to send troops to Vietnam, but only 33 percent of grade school-educated people were so willing.
