Fighting Voter Suppression
League of Women Voters of Massachusetts v. Trump
On March 31, 2026, President Trump issued a sweeping Executive Order titled "Ensuring Citizen Verification and Integrity in Federal Elections," seeking once again to seize control of election administration from Congress and the states. The Order directs federal agencies to compile lists of U.S. citizens and transmit them to states before every election, directs the U.S. Postal Service -- an independent agency established by Congress -- to create a list of "approved" mail voters, and instructs USPS to refuse to deliver ballots from voters not on that federally created list. If implemented, the Order would threaten the ability of millions of eligible citizens to cast their ballots, particularly military members, overseas citizens, the elderly, recently naturalized citizens, and voters with disabilities who rely on mail voting.

Coalition for Open Democracy v. Scanlan
This lawsuit challenges HB 1569, a new law that will make New Hampshire the only state to require every person to produce documentary proof of citizenship when they register to vote for both state and federal elections. It also challenges HB 1569’s elimination a preexisting protection for voters—namely, an affidavit option that allowed voters who faced surprise challenges to their eligibility at the polls to swear to their qualifications and cast a ballot. Accordingly, HB 1569 violates the First and Fourteenth Amendments of the U.S. Constitution by placing substantial burdens on New Hampshirites at all stages of the voting process, and will arbitrarily disenfranchise hundreds, if not thousands of qualified voters.

League of Women Voters Education Fund v. Trump
On March 25, 2025, in a sweeping and unprecedented Executive Order, President Trump attempted to usurp the power to regulate federal elections from Congress and the States. Among other things, the Executive Order directs the Election Assistance Commission—an agency that Congress specifically established to be bipartisan and independent—to require voters to show a passport or other citizenship documentation in order to register to vote in federal elections. If implemented, the Executive Order would threaten the ability of millions of eligible Americans to register and vote and upend the administration of federal elections.
On behalf of leading voter registration organizations and advocacy organizations, the ACLU and co-counsel filed a lawsuit to block the Executive Order as an unconstitutional power grab.

Ayota v. Fall
On October 31, 2024, just five days before the November 5 General Election, Cobb County announced that it had failed to send more than 3,000 absentee ballots to Cobb County voters who had timely requested them. Many of these voters are at school hundreds of miles away or have disabilities that make it all but impossible to vote in person. The ACLU and co-counsel sued on behalf of affected voters to ensure that they would not be disenfranchised because of the County's administrative error.

American Civil Liberties Union of South Carolina v. State Election Commission
The South Carolina Department of Motor Vehicles (SCDMV) has unlawfully denied young, eligible South Carolinians the opportunity to register to vote. Under South Carolina law, individuals who are 17 years old may register to vote and vote in primary elections so long as they (1) will turn 18 on or before the next general election, and (2) otherwise meet the qualifications for voting. An administrative error in the SCDMV's processes, however has stopped the Department from transmitting the proper paperwork to complete all registration information to the South Carolina Elections Commission. As a result, thousands of young voters who did everything right and should have been registered to vote have not been added to the state's voter rolls in the runup to the 2024 general election. ACLU and ACLU of South Carolina sued, asking the court to ensure that these new voters are registered and properly notified in time for them to vote in the November 2024 election.

On the eve of the November 2024 presidential election, a third-party organization has challenged about 20,000 voters in Clark County, Nevada on the basis of purportedly improper residency. When Clark County rightly declined to process these challenges as improper under Nevada law, the third-party organization sued to compel the county to act on the challenges. The ACLU Voting Rights Project and the ACLU of Nevada have moved to intervene in the case to prevent mass disenfranchisement of Clark County voters mere weeks out from the 2024 general election.
