“I do think that the passing of Ruth Bader Ginsburg has galvanized eligible voters, in particular, who understand the role of the Supreme Court and are concerned about the future of civil rights,” Carolyn DeWitt, president of Rock the Vote, told CNBC on Tuesday.

Vote.org, a nonpartisan nonprofit that allows people to register through its website, processed more than 40,000 new voter registrations on Saturday and Sunday, a 68% increase from the prior weekend, according to its spokesman. The website saw more than 35,000 mail ballot requests on Saturday and Sunday, a 42% increase from a week earlier.

On National Voter Registration Day, Vote.org processed over 74,000 new voter registrations and 41,000 mail-in ballot requests. After the story was first published, the group later provided CNBC with their key final data points for what turned out to be a historic day. In the full 24 hours of National Voter Registration Day, Vote.org registered 135,000 new voters. That’s double their voter registration day success during the 2018 elections.
