Voter ID has proved as contentious in Missouri as anywhere with new lawsuit only latest turn. A new article at Reuters by Timothy Mclaughlin in their Chicago office had the story:

Civil rights groups have sued Missouri to prevent its new voter identification law from interfering with a local special election next month, saying the measure could disenfranchise voters. The lawsuit seeks a court order blocking the law from remaining in effect during the July 11 special election for an alderman in St. Louis.

The lawsuit was filed on Thursday in the Cole County Circuit Court in Jefferson City by the American Civil Liberties Union and the Advancement Project on behalf of the NAACP and the League of Women Voters of Missouri. Missouri has failed to provide necessary mandated funding for voter education, free voter IDs and birth certificates and training for poll workers since the new voting law came into effect on June 1, the ACLU said in the lawsuit.

It was only in November that the law was passed. According to an old post at Mother Jones:

By a 63-37 percent margin, Missouri voters passed a constitutional amendment to require photo identification to vote. Missouri could become the next state to require voters to bring a government-issued photo ID to cast a ballot.

The referendum on the ballot asks voters to decide whether to amend the state constitution and permit legislators to pass voter ID laws, a decade after the state Supreme Court declared the practice unconstitutional. In the 2006 case, Weinschenk v. Missouri, the court ruled the law “creates a heavy burden on the fundamental right to vote.” If the measure passes, it would go into effect in January, and Missouri would join 31 other states that require some sort of identification to vote. Voter ID laws are part of state-level voting restrictions enacted after the 2013 Shelby County v. Holder decision, in which the Supreme Court gutted a number of key components of the 1965 Voting Rights Act.
