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?"
