STUDY CONTENT HIGHLIGHTS:
In addition to content on electoral participation, voting behavior, and public opinion, the 1968 ANES contains questions in other areas such as political trust and political efficacy. Topical content includes questions about integration, Vietnam, the 1968 Democratic Convention, and the independent Presidential candidate George Wallace. Among special-interest items are new issue scales on Vietnam policy and urban unrest, new questions on protest, civil disobedience, and confidence in government at different levels, a battery on various educational problems, and the first use of feeling thermometers for political figures.

STUDY DESIGN HIGHLIGHTS:
The 1,673 total interviews in the 1968 ANES include not only a traditional time series national cross-section, but also a supplement of 116 eligible black voters. The black supplement alone is not usable as a valid sample, but is intended for use together with the cross-section to create a combined sample, or with black respondents from the cross-section to produce a larger all-black sample. Because the black supplement portion of the combined sample slightly under-represents blacks in mixed neighborhoods, the combined sample is usable for cross-section analysis with exception for analysis on questions in which the racial environment might have an influence on the respondent's answer.

A feature of the post-election survey was the mailing of two-page mail questionnaires to respondents who were noninterviews in the post, in an attempt to compensate for a lower than expected re-interview rate. The mail questionnaire, which covered 1968 voting behavior, was sent out to 182 persons, yielding 36 additional post-election responses.

Beginning September 6, interviews using the 80-minute pre-election instrument were conducted prior to Election Day, November 5. The 80-minute post-election interview was administered November 6, 1968-February 24, 1969. For the cross-section, 2,011 eligible cases yielded 1,557 pre-election completions and 1,384 post-election re-interviews.

WEIGHTS SUMMARY:
V680003 is an integer weight required when using the combined sample or all-black sample. The 1970 cross-section sample is unweighted. The sample selection filter for the cross-section and all-black sample is V680004.
