The US supreme court appeared poised on Monday to curtail how mail-in ballots can be counted if they arrive after election day, which would affect laws in more than a dozen states during a midterm election year.
The justices are considering Watson v Republican National Committee, a challenge over a Mississippi state law that was brought in 2024 by the Republican party. Mississippi allows mailed ballots to be counted if they arrive within five business days of election day, so long as they were postmarked by election day. Mississippi changed its laws in 2020, during the Covid-19 pandemic.
