Notes
RULING HAS NOT YET DROPPED as of this run (June 1, 2026). Expected late June or early July. Affects 14 states + D.C. If the Court rules against the grace period, it will land potentially weeks before some state primaries and months before the November general election. This is the highest-priority live watch item in this report.
Coverage Gap
No significant gap. Full spectrum coverage post-oral arguments.
