Federal election observers can only be sent to five states in this year's U.S. presidential election, among the smallest deployments since the Voting Rights Act was passed in 1965 to end racial discrimination at the ballot box. The plan ... reflects changes brought about by the Supreme Court's 2013 decision to strike down parts of the Act, a signature legislative achievement of the 1960s civil rights movement. Voting rights advocates told Reuters they were concerned that the scaling-back of observers would make it harder to detect and counter efforts to intimidate or hinder voters, especially in southern states with a history of racial discrimination at the ballot box. The Supreme Court ruling undercut ... the Justice Department's ability to select voting areas it deemed at risk of racial discrimination and deploy observers there. Eleven mostly Southern states had been certified as needing federal observers by the department. Federal observers can still be sent to monitor elections but only when authorized by federal court rulings. Currently, courts have done so in five states: Alabama, Alaska, California, Louisiana, and New York, according to the Justice Department. In recent presidential elections, the Justice Department has sent more than 780 people to watch elections around the country. Attorney General Loretta Lynch said on Friday the Justice Department's ability to deploy election observers had been severely curtailed" by the Supreme Court's decision.
