USA Today's Fredreka Schouten reports (6/20/11) on states adopting photo ID laws to crack down on the nearly non-existent problem of voter fraud. Schouten lays out the argument:
Proponents say the measures prevent vote fraud. Opponents say they are designed to stifle turnout among students, poor people and minorities, who are more likely to vote for Democrats but might lack government-issued IDs, such as driver's licenses and passports.
Actually most opponents tend to point out that there is no voter fraud problem. Any decent report on this subject would point this out– otherwise readers are left with the impression that Republicans want to maintain the integrity of the vote, and Democrats are upset that they'll lose some of their supporters.
