Supreme Court to rule on counting late mail ballots amid grace-period debates

The Supreme Court will decide in Watson v. RNC whether Mississippi’s and similar states’ post-Election Day deadlines for counting mail ballots conflict with federal election laws, potentially affecting 14 states and military/overseas voters using grace periods. The ruling could reshape how late ballots are treated ahead of the November midterms, amid ongoing political battles over mail voting; a decision is expected by late June or early July, which could force states to adjust deadlines and voter education if grace periods are struck down.
