 African Americans who had been barred from registering to vote finally had an alternative to taking suits to local or state courts, which had seldom prosecuted their cases to success.If discrimination in voter registration occurred, the 1965 act authorized the Attorney General of the United States to send Federal examiners to replace local registrars.Within months of the bill's passage, 250,000 new black voters had been registered, one-third of them by federal examiners.
