One group said it has registered over 100,000 new voters since U.S. President Joe Biden dropped out of the 2024 race.

The group behind a popular get-out-the-vote technology platform said Friday that it’s registered more than 100,000 new U.S. voters since President Joe Biden withdrew from the 2024 presidential race, a surge that came amid mounting Republican efforts to make it harder to register and vote.

Vote.org said that 84% of voters registered in the new wave are under age 35. Nearly 1 in 5 new registrees is 18 years old. Andrea Hailey, the group’s CEO, said that “since 2020, we have led the largest voter registration drive in U.S. history,” with more than 7.8 million people registered.

After dropping out, Biden endorsed Vice President Kamala Harris to face former Republican President Donald Trump and Sen. JD Vance (R-Ohio) in the November election. The new presumptive Democratic candidate has already earned endorsements from many Democrats in Congress and groups advocating on issues including climate, labor, and reproductive rights.

Vote.org’s success comes as Republicans at the federal level are proposing and passing legislation creating obstacles to the ballot box.

Earlier this month, U.S. House Republicans passed Rep. Chip Roy’s (R-Texas) Safeguard American Voter Eligibility (SAVE) Act, which would require proof of American citizenship to vote in federal elections. Republicans claim the bill is meant to fix the virtually nonexistent “problem” of noncitizen voter fraud.

However, Rep. Summer Lee (D-Pa.) slammed the bill as a “xenophobic attack” meant to silence “Black voices, brown voices, LBGTQIA+ voices, [and] young voices.”

Lee said the SAVE Act underscores the need to pass her recently introduced Right to Vote Act, “which would establish the first-ever affirmative federal voting rights guarantee, ensuring every citizen may exercise their fundamental right to cast a ballot.”

Earlier this year, U.S. Senate Democrats also reintroduced the John R. Lewis Voting Rights Advancement Act, legislation its sponsors say will “update and restore critical safeguards of the original Voting Rights Act.”

Meanwhile, Republican-controlled state legislatures and red-state governors are enacting laws imposing tough restrictions on voter registration, with violations punishable by stiff fines that critics say are meant to dissuade people from registration drives and similar efforts.

Again under the guise of preventing fraud, Republican Florida Gov. Ron DeSantis last year signed legislation limiting voter registration drives, with fines of up to $250,000 for violators.

“These draconian laws and rules are like taking a sledgehammer to hit a flea,” Cecile Scoon, an attorney and president of the Florida chapter of the League of Women Voters, toldThe New York Times in an article published Friday.

Three years after Kansas passed a law making “false representation” of an election official a crime, campaigners say it’s become extremely difficult to sign up new voters.

“In 2020, even with the pandemic, we had registered nearly 10,000 Kansans to vote. Now, we haven’t been able to register anyone,” Davis Hammet, president of the youth voter mobilization group Loud Light, told the Times.
