Respondents were asked: "Some people argue that requiring registered voters to present government-issued photo identification at the polls reduces voter fraud and does not place major obstacles on anyone who is legally entitled to vote. Other people argue that such a requirement has a negligible effect on voter fraud but places significant obstacles on elderly, low-income, disabled, and minority voters. Do you agree or disagree with the idea that registered voters should be required to present a government issued photo ID at the polls before they can be allowed to vote?"
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.
