USPS finalizes federal mail-ballot eligibility rules while two injunctions stand

The sentence with operational teeth in the notice is not the one about eligibility lists. It is the objection USPS printed and declined to resolve: that the Postal Service "would refuse to accept certain ballots for federal elections that states tender without satisfying the data-entry obligations that the rule would impose" ^[9]. CyberScoop reports that election experts have raised the same concern in interviews ^[9].

Strip the constitutional argument out and what remains is a data pipeline requirement. Somebody keys voter records into a federally defined form, on a schedule, to an accuracy standard, and if that step is missed the ballots a state has lawfully issued may not be accepted ^[9]. The notice as reported does not settle who does that keying, in what format, or by when. That is the part county offices and the vendors running their voter files would need in order to scope work, and it is the part that is missing.

USPS has also drawn a line it may not be able to hold. The rule carries an immediate effective date because, in the agency's words, "delaying the effective date would jeopardize implementation of this rule in time for the 2026 general election, which will be held on November 3, 2026" ^[6]. The same agency says it will not implement until the Supreme Court rules ^[4]. Those two statements together concede the point that matters to administrators: compliance work has a lead time long enough that a rule cannot be stood up on short notice ^[15]. Whatever lead time USPS needs, the states tendering the ballots need at least as much, and they do not get a stay on their own preparation while the appeal runs.

On the merits, USPS moved its ground. The notice argues that "whether or not voter fraud is common or uncommon, the Postal Service has the legal authority to take the measures in this rule" ^[11], while presenting no credible evidence of coordinated mail-in voter fraud ^[10]. By the agency's own account, the supportive comments largely concern the perception that fraud is a significant problem, with phrases such as "strengthens confidence" and "reduce uncertainty" running through them ^[8]. So the justification on the record is authority plus perception, not a documented finding ^[16].

The comment file is similarly unusable as a scoreboard. The notice reports 200,000 comments and gives no breakdown between support and opposition ^[7], and it sets aside submissions it characterises as partisan speculation, including those about turnout effects, as exceeding the scope of the proceeding ^[12].

Meanwhile the law has not moved. The District of Massachusetts issued a second, separate injunction last week, with Judge Indira Talwani writing that "the executive branch has no authority to regulate elections" ^[3]. It is not clear whether the Supreme Court will take both injunctions in one ruling or separately before election day ^[13]. Michael McNulty of Issue One said voters can continue to rely on the rules their state has established unless and until a court orders otherwise ^[14].
