A Technical Postmark Rule and the Right to Vote in a Pandemic
How RNC v. DNC turned a deadline question into a choice between health and the franchise during Wisconsin's 2020 primary.
On the evening of April 6, 2020, the Supreme Court stayed a federal injunction that would have let Wisconsin count absentee ballots mailed after election day, hours before polling places opened for the state’s spring primary. The order in Republican National Committee v. Democratic National Committee, 589 U.S. ___ (2020), framed itself as the answer to a “narrow, technical question” about postmark deadlines. Its practical effect was anything but narrow: voters who had asked for absentee ballots that election officials had not yet been able to mail were left to choose between forgoing their vote and standing in line during the early weeks of a viral pandemic. The gap between the order’s modest self-description and its consequences on the ground is what makes the decision a durable reference point in the law of election emergencies.
How an ordinary primary became a constitutional emergency
Wisconsin’s spring election was scheduled for April 7, 2020, carrying a presidential preference vote, a state supreme court race, and thousands of local contests. As COVID-19 spread, absentee requests surged to levels the state’s clerks had never processed. Roughly a million more voters sought mailed ballots than in the comparable 2016 cycle, and local election offices fell behind in printing, addressing, and mailing them. The shortfall was not theoretical: ballots that had been timely requested under existing deadlines simply had not gone out in time for voters to return them by the close of polls.
Several Wisconsin voters, community organizations, and the state and national Democratic parties sued members of the Wisconsin Elections Commission in the Western District of Wisconsin. The consolidated litigation, captioned Democratic National Committee v. Bostelmann, sought relief easing the pandemic’s effects on the election, including a longer window to request ballots and a relaxed witness-certification requirement for absentee voters who could not safely find a witness. The district court granted a preliminary injunction; the relevant piece for the Supreme Court was an extension allowing absentee ballots to be received and counted through April 13, six days after election day.
The “narrow, technical question” the majority chose to answer
The per curiam opinion declined to engage the broader constitutional balance and instead isolated a single procedural point. As the Court put it, the question was “whether absentee ballots now must be mailed and postmarked by election day, Tuesday, April 7, as state law would necessarily require, or instead may be mailed and postmarked after election day, so long as they are received by Monday, April 13.” Confined that way, the dispute looked like a quarrel over a calendar entry rather than a contest over access to the franchise.
The majority leaned heavily on a procedural feature of the record: the plaintiffs, it noted, “did not ask that the District Court allow ballots mailed and postmarked after election day, April 7, to be counted.” On that reasoning, the district court had granted relief broader than what the parties requested, and a stay was warranted to restore the postmark rule. The framing mattered. By treating the case as a question of whether a court could extend a postmark deadline that no one had moved to extend, the Court avoided weighing the burden the in-person alternative imposed on voters whose ballots had not yet been mailed.
Purcell and the eve-of-election rule
The decision is most often cited for its application of the so-called Purcell principle, drawn from Purcell v. Gonzalez, 549 U.S. 1 (2006). The Court reiterated that “lower federal courts should ordinarily not alter the election rules on the eve of an election,” reasoning that late changes risk confusing voters and election administrators. In the abstract, the concern is legitimate: rules that shift days before ballots are cast can produce inconsistent treatment and erode confidence in the count.
Yet the eve-of-election timing cut in both directions. The pandemic itself was the late-breaking change in circumstances, and the relief sought was an accommodation to it rather than a partisan rewrite of settled rules. The majority’s reliance on stability assumed a baseline that the public-health emergency had already disrupted. Notably, the per curiam did not apply the Anderson-Burdick framework — the balancing of voter burden against state interest that the district court had used under Anderson v. Celebrezze, 460 U.S. 780 (1983), and Burdick v. Takushi, 504 U.S. 428 (1992). That omission left the asserted interest in deadline regularity facing little explicit weight on the other side of the scale.
The dissent: a deadline waiver that counted real ballots
Justice Ginsburg, joined by Justices Breyer, Sotomayor, and Kagan, read the stakes as concrete rather than technical. The point of the deadline extension, the dissent explained, was to count ballots from voters who had done everything right and were waiting on a system that could not keep pace. As of the Sunday before the election, the dissent observed, a substantial number of requested ballots reportedly had not yet been mailed, and tens of thousands of voters who timely requested ballots were unlikely to receive them in time to postmark by April 7.
On those facts, the dissent argued, the majority’s postmark rule did not preserve the status quo so much as guarantee that lawfully requested ballots would go uncounted. The choice it forced — risk infection by voting in person or lose the franchise — was, in the dissent’s view, the kind of “massive disenfranchisement” that ordinary deadline rules were never meant to produce. The disagreement was less about the Purcell principle in the abstract than about whether a court confronting an administrative breakdown could treat a receipt-date extension as a modest, stabilizing accommodation rather than a forbidden last-minute change.
Almost the entire dispute turned on how the question was characterized. Cast as “may a court move a postmark deadline no party moved to extend,” the answer leaned toward a stay. Cast as “may lawfully requested ballots be counted when the state could not mail them in time,” the answer leaned the other way. The opinion’s durability comes from how visibly the legal result followed from that choice of frame.
What Wisconsin’s election looked like on the ground
The on-the-ground consequences sharpened the doctrinal debate. In Milwaukee, the state’s largest and most diverse city, the number of polling places collapsed from roughly 180 to a handful as poll workers declined to serve amid the outbreak. Voters waited in long lines, and turnout fell most steeply in wards with larger Black and Hispanic populations. Empirical work published afterward attributed measurable turnout declines to the consolidation of polling sites, with the sharpest effects concentrated among the voters least able to absorb them. The combination — fewer in-person options and a hard postmark deadline for absentee ballots that had not all been mailed — is what gave the “risking death to vote” description its force.
The decision’s afterlife in pandemic election law
The order became an early and influential marker for how federal courts would treat 2020’s wave of election-emergency litigation. Courts repeatedly invoked the Purcell principle to stay or narrow district-court accommodations as elections approached, and the question of how close is “too close” to election day recurred throughout the cycle. The breadth and operation of Purcell remained contested, and later separate writings by individual Justices disagreed about whether it functions as a near-categorical bar or one factor among several. The Supreme Court has not resolved that tension in a majority opinion, leaving the precise weight of the principle unsettled.
What endures from RNC v. DNC is the cautionary lesson about characterization. A dispute over receipt dates can determine whether tens of thousands of timely requested ballots are counted, and the labels a court selects can decide the outcome before any balancing begins. For readers tracking how emergency powers, public-health constraints, and the right to vote intersect, the case sits alongside other moments when pandemic conditions reshaped ordinary legal rules — a thread this publication has followed in its commentary and in coverage of how the crisis altered familiar arrangements, including how emergencies redraw who bears public burdens. The current outlines of the Purcell principle, and the proper role of Anderson-Burdick balancing alongside it, are matters readers can follow on the case tracker.
Questions readers ask
What did the Supreme Court actually decide in RNC v. DNC?
It stayed part of a federal district-court injunction, restoring Wisconsin’s rule that absentee ballots be mailed and postmarked by election day, April 7, 2020, rather than counted if received by April 13. The Court characterized this as resolving a narrow, technical question about postmark deadlines.
Why is the case described as forcing a choice between health and the vote?
Many voters had timely requested absentee ballots that election officials had not yet mailed. With the postmark deadline restored and in-person polling sites sharply reduced, those voters faced either appearing in person during the early pandemic or losing the chance to vote at all.
What is the Purcell principle?
It is the idea, drawn from Purcell v. Gonzalez (2006), that lower federal courts should ordinarily not alter election rules on the eve of an election, because late changes can confuse voters and administrators. The Court relied on it to justify the stay.
Did the Court apply the usual voter-burden balancing test?
No. The per curiam did not apply the Anderson-Burdick framework, which weighs the burden on voters against the state’s interests. The district court had relied on that framework; the Supreme Court’s order did not engage it directly.
What was the majority’s main procedural point?
The Court emphasized that the plaintiffs had not asked the district court to allow ballots mailed and postmarked after election day to be counted, so the injunction granted relief broader than what was requested.
What did the dissent argue?
Justice Ginsburg, joined by three colleagues, argued that the deadline extension was needed to count ballots from voters who had done everything required but were waiting on an overwhelmed mail system, and that the majority’s rule risked widespread disenfranchisement.
How many ballots were affected?
The dissent noted that a substantial number of requested ballots had reportedly not yet been mailed by the Sunday before the election, and that tens of thousands of voters who timely requested ballots were unlikely to receive them in time to meet the postmark deadline. Precise final totals of uncounted ballots are difficult to state with confidence.
What happened in Milwaukee on election day?
The number of polling places fell dramatically as poll workers withdrew, producing long lines. Studies afterward associated the consolidation with reduced turnout, with the largest declines in wards with greater Black and Hispanic populations.
Is the Purcell principle settled law?
Its core idea is well established, but its precise weight is not. Justices have disagreed in later writings about whether it operates as a near-categorical bar or as one consideration among several, and no majority opinion has fully resolved the question.
Did the witness-certification requirement survive?
The witness-certification issue was part of the broader litigation rather than the postmark question the Supreme Court resolved here. The stay order addressed the receipt-date extension; other accommodations were litigated separately and reached different outcomes.
