With just 54 days until Americans go to the polls to elect the next leader of the free world, new research suggests that election turnout among young African Americans, Latinos and Native Americans may drop by nearly 700,000 voters in states with new photo ID laws. 

Researchers said the decline could potentially impact the presidential contests in the battleground states of Florida and Pennsylvania.

Researchers Jon C. Rogowski and Cathy Cohen found that turnout among young minority voters in states with new restrictive ID laws could fall below 2004 and 2008 levels. 

"We know from a variety of recent studies that young people and people of color - especially African Americans - possess state-issued photo identification cards at much lower rates than whites," Rogowski said. "These new photo identification laws, then, are likely to significantly reduce overall levels of turnout among young people, and especially among young people of color."

According to the study, the new laws may impact the presidential contest, as well as at least 15 competitive House races across the country where photo identification requirements will likely disproportionately impact minority voters.

"The photo ID laws may have direct electoral implications," Rogowski said. "Not only could they dilute the political potency of young people of color, but they also have the potential to shift outcomes in competitive races. Control of the White House and the Senate could be at stake."

In Florida, a crucial battleground state in the presidential race, voters are required to show photo identification or some other form of ID that displays a signature. 

More than 100,000 youths of color in the state could be demobilized by these new voting requirements - far more votes than separated George W. Bush and Al Gore in the 2000 presidential election.

Over the last two years, more than 66 percent of the nation's 50 states have sought to increase restrictions on the kinds of identification that citizens must show before being allowed to vote, according to the report. As a result, nine states now have laws requiring citizens to show government-issued photo identification before casting a ballot. Eight other states enacted similar measures, but offer a limited set of alternatives for those without IDs. Only two of these laws were enacted prior to the 2008 election.

Some of the photo ID proposals have been defeated or denied.  

The U.S. Department of Justice invoked the Voting Rights Act and refused to grant clearance to laws passed in South Carolina and Texas, and the Wisconsin law was declared unconstitutional earlier this year. Legal action is ongoing in other states, including Pennsylvania, with civil rights and social justice organizations offering strong opposition to the measures that are likely to restrict voting.

"Engaging young people-our future leaders-in the political process and motivating them to vote should be among our highest priorities as a democracy," Marc H. Morial, president and CEO of the National Urban League, said. "While we are disheartened to see the apparently systematic way in which the minority youth vote is being undermined, we are committed to meeting this assault with redoubled efforts to ensure that everyone who is eligible to vote can and does vote. Nothing less than the future of our political process is at stake."

Judith Browne Dianis, co-director of the Advancement Project, expressed concern over the laws. "The voting booth is the one place in America where everyone has an equal voice," said Browne Dianis, whose organization is engaged in the legal battles over the photo ID laws in the states. "It's wrong for politicians to manipulate election laws for their own partisan gain. These photo ID laws have a disproportionate impact on people of color, so if we want our country to live up to its democratic ideals, then our voting system must be free, fair and accessible to all eligible Americans."

Meanwhile, the report estimated that if Pennsylvania's photo identification law is upheld by the State Supreme Court, 37,000 to 44,000 young people of color may stay home or be denied the right to vote, significantly influencing the state's presidential contest.

While these laws are likely to disproportionately demobilize all youth of color, they may have more severe consequences for young blacks. Citing data from the Brennan Center for Justice at the New York University School of Law, the report said that 11 percent of American citizens don't have government-issued photo identification such as a driver's license, state ID card, military ID or a passport. But only nine percent of whites lacked photo identification, compared with 16 percent of Latinos and 25 percent of blacks.

Florida, Georgia, Pennsylvania, and Texas have the largest pools of potential young Latino voters, though Latinos also comprise significant portions of the youth electorate in states like Tennessee and Wisconsin as Should Latinos turn out to vote at rates similar to 2004, between 68,000 to nearly 200,000 Latinos could be demobilized across these states. And should they turn out to vote at rates similar to 2008, the estimated effect could be greater than 250,000. One hundred thousand Latino youth in Texas alone, for instance, could be demobilized as a consequence of these new voting restrictions.
