With Pennsylvania’s latest upheaval over what voters must take to the polls next month, the state joins a series of battles across the country where opponents of photo ID laws have seen success for the current election cycle. Challengers have garnered temporary victories against photo ID laws here, as well as in Texas and Wisconsin. Federal officials also halted laws in Mississippi, and likely South Carolina, from going into effect this year. While a weak lawsuit against Tennessee’s tough ID law was tossed aside and a stringent ID card referendum still awaits Minnesota voters, opponents note that the ballot measure in Minnesota only drew support from 52 percent of respondents in a recent poll. “In most cases, the challengers aren’t losing; they’ve generally been successful,” said Keesha Gaskins, senior counsel for the Brennan Center for Justice, which has been critical of voter ID laws.
