IN THE last four years, half-dozen states have added laws that require voters to present a government-issued photo ID in order to cast a ballot in an election. Opponents say it disenfranchises poor and minority voters, while proponents say it's needed to stem voter fraud.
In 30 states across the county, when voters hit the polls this year, they'll be required to present identification.
Already there have been examples of perfectly legal voters who have been turned away because they were unable to get the ID needed to vote.
States that request or require a photo ID: Georgia, Indiana, Kansas, Mississippi, South Carolina, Tennessee, Texas, Alabama, Florida, Hawaii, Idaho, Louisiana, Michigan, South Dakota and Wisconsin
States that require ID - photo not required: Alaska, Arizona, Arkansas, Colorado, Connecticut, Delaware, Kentucky, Missouri, Montana, North Dakota, Ohio, Oklahoma, Rhode Island, Utah, Virginia and Washington
