The ACLU and Advancement Project are suing Missouri over its new voter ID law, charging it fails to provide mandated funding for voter education, free voter IDs and birth certificates, and training of poll workers.

U.S. Election Assistance Commission Executive Director Brian D. Newby’s action to allow three states to require documentary proof of citizenship on the federal voter registration form is illegal, argued the League of Women Voters of the United States, along with its Alabama, Georgia, and Kansas state Leagues, and others in a suit filed today in federal court.

Wisconsin’s voter ID law is one of the harshest in the country and requires voters to produce one of a few specified forms of photo identification in order to vote. This restriction imposes a substantial burden on the right to vote by requiring photo identification that many voters do not have, and that many voters cannot easily obtain, in violation of the Fourteenth Amendment of the Constitution. In addition, the Wisconsin voter ID law violates Section 2 of the Voting Rights Act, which prohibits the use of voting practices that have a negative impact on racial and language minorities. The law has a disproportionate impact on black and Latino voters, who are twice as likely to lack photo ID accepted for voting in Wisconsin compared to white voters.
