On September 9, this reply brief was filed in the Fourth Circuit in Baten v McMaster, 19-1297. The issue is whether the U.S. Constitution bars states from electing presidential electors on an at-large basis. This brief was filed by the opponents of at-large elections. The case will now be set for oral argument. It is one of four similar cases. The others are in Massachusetts, Texas, and California.
Briefing is complete in the California case, and it may be argued as early as January 2020. Briefing is still not completed in the Texas case. The Massachusetts case was argued September 10, 2019. All four of these cases lost in U.S. District Court.
