Case Preview: Watson v. RNC | Can States Accept Mail Ballots After Election Day?

Watson v. Republican National Committee | Case No. 24-1260 | Docket Link: Here | Oral Argument: 3/23/26

Question Presented: Whether federal election-day statutes preempt state laws allowing ballots cast by election day to arrive after that day.

Overview: Mississippi allows mail ballots postmarked by election day to count if received within five business days after. Republicans challenge this under federal statutes setting election day, raising fundamental questions about mail voting nationwide.

Posture: District court upheld Mississippi law; Fifth Circuit reversed unanimously; Supreme Court granted certiorari November 2025.

Main Arguments:

1. Petitioner (Mississippi): (1) "Election" means voters' conclusive choice when casting ballots, not officials' receipt afterward; (2) Counting lawfully occurs post-election day, so receipt can too; (3) Nearly thirty states permit post-election receipt; invalidating these laws disenfranchises military voters protected under UOCAVA.
2. Respondents (RNC): (1) "Election" means state's public process of selecting officers, concluding when officials close ballot box and receive final ballots; (2) Every Civil War-era soldier-voting law required election-day receipt despite early voting; (3) UOCAVA creates narrow exception proving baseline rule requires election-day receipt.

Implications: Petitioner victory preserves mail-ballot practices in nearly thirty states and protects military voters relying on extended receipt deadlines under federal law. Respondent victory requires states to receive all ballots by election day, potentially disenfranchising voters facing mail delays and invalidating extended military-ballot protections, forcing nationwide restructuring of absentee voting systems before next federal election.

The Fine Print:

1. 2 U.S.C. § 7: "The Tuesday next after the 1st Monday in November, in every even numbered year, is established as the day for the election, in each of the States and Territories of the United States, of Representatives and Delegates to the Congress"
2. Mississippi Code § 23-15-637(1)(a): Mail ballots "postmarked on or before the date of the election and received by the registrar no more than five (5) business days after the election" count toward final tallies

Primary Cases:

1. Foster v. Love (1997): Federal election-day statutes mandate holding all elections for Congress and Presidency on single day throughout Union; Louisiana's open-primary system allowing October final selection violated federal requirement.
2. Republican National Committee v. Democratic National Committee (2020): Court recognized ballot "casting" as fundamental to elections; reversed district court decision permitting voters to mail ballots after election day during pandemic.
