Estimated SCOTUS Lineup

Because this application lands 24 days prior to Election Day after ballots have already been distributed to voters, the conservative supermajority is primed to invoke the Purcell principle to prevent last-minute alterations, or alternatively halt lower court modifications of state legislative enactments.

Purcell Principle Temporal Proximity Gauge

Purcell v. Gonzalez (2006): Lower federal court orders altering ballot mechanisms immediately before voting are disfavored.
Severe Anti-Disruption Zone (< 30d)
Election Day (0d) Critical 15d Early Mail Out 45d 60d Safe Harbor 90d+ Regular Docket
Litigation Consequence: At 24 days out, SCOTUS routinely freezes lower court injunctions that liberalized or invalidated strict statutory envelope requirements, even when civil rights claims are substantial, to preserve administrative status quo.
