On January 30, the U.S. Supreme Court said it will hear Watson v Republican National Committee, 24-1260, on Monday, March 23. This is the case in which the Fifth Circuit ruled that Mississippi can’t accept postal ballots that arrive later than election day. The Fifth Circuit based its decision on the 1872 federal law that sets congressional election day as the first Tuesday after the first Monday in November. No other court, and no administrative agency, had ever interpreted that law to mean that all ballots must be in the elections office by federal election day.
