The docket in RNC v. Genser is here. Politico reports on the case here:

The Democratic National Committee is ramping up its fight with the GOP over voting rights, urging the Supreme Court to reject Republicans’ efforts to limit provisional voting in Pennsylvania.

The brief, first shared with POLITICO, argues that the high court lacks jurisdiction to hear the case and that doing so would burden the court with requests to take up “any and every state-law election” dispute in the future.

The Republican National Committee is asking the Supreme Court to overturn a decision by Pennsylvania’s highest court that allows voters to use provisional ballots if their mail ballots have been rejected. Republicans argued that the Pennsylvania Supreme Court had usurped the state legislature’s power to regulate elections when the justices ruled that such provisional ballots must be counted.
