Following March 23 oral arguments in a Republican National Committee challenge to Mississippi's law allowing mail-in ballots postmarked by Election Day to be received up to five days later, Supreme Court justices—including several conservatives—signaled strong skepticism toward state grace periods, emphasizing federal statutes like 2 U.S.C. § 7 that designate a uniform Election Day for federal elections. Justice Alito highlighted that Election Day functions as a single date for voting, not an extended period, raising prospects of a nationwide bar on post-Election Day counting. With a decision anticipated by late June ahead of 2026 midterms, traders price Yes at 72.5% based on this conservative majority's apparent consensus, though liberal justices voiced concerns over voter disenfranchisement and states' election administration authority under Article I, Section 4. Local officials warn of potential processing chaos in states like Pennsylvania and California.
