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?"
Measurement of Party ID for this figure is based on two questions. First, respondents were asked whether they consider themselves to be a Democrats, Republicans, independents, other, or not sure. Those who responded that they are independents or "other" were then asked if they lean toward either the Democrats or Republicans. If they indicated that they lean toward one party or the other, they are considered Democrats or Republicans for the purposes of this figure. Only "pure" independents or members of a third party who indicate that they have no preference for Democrats vis-a-vis Republicans are considered independents . Respondents who answered that they are "not sure" for either of the two aforementioned questions are not incorporated into this figure.
