Respondents were asked, "As you may know, some states have a history of discrimination in their election laws. Because of this, they are required to request federal approval before implementing any changes to their voting procedures or election practices. Do you think these states should still be subject to federal supervision, or do you think they should be able to change their voting and election practices without the approval of the federal government?"
The ideology measure is based on respondent self-placement in response to the following question: "On a scale from 1 to 7, where 1 is extremely liberal, 7 is extremely conservative, and 4 is exactly in the middle, where would you place yourself?" For the purposes of this table, respondents placing themselves 1, 2, or 3 are considered "liberal"; those placing themselves at 5, 6, or 7 are considered "conservative"; and those placing themselves at 4 are considered "moderate".
