On August 6, 1965, the Democrat signed the law. From Wikipedia: "The Voting Rights Act of 1965 (42 U.S.C. §§ 1973–1973aa-6) is a landmark piece of national legislation in the United States that outlawed discriminatory voting practices that had been responsible for the widespread disenfranchisement of African Americans in the U.S. Echoing the language of the 15th Amendment, the Act prohibits states from imposing any 'voting qualification or prerequisite to voting, or standard, practice, or procedure....to deny or abridge the right of any citizen of the United States to vote on account of race or color.' Specifically, Congress intended the Act to outlaw the practice of requiring otherwise qualified voters to pass literacy tests in order to register to vote, a principal means by which Southern states had prevented African-Americans from exercising the franchise."
