The U.S. Supreme Court is currently deliberating several significant cases regarding mail-in ballot laws, particularly concerning a challenge from GOP Congressman Mike Bost related to voting procedures in Illinois. Justices appear receptive to allowing candidates greater latitude in contesting state election laws, with discussions indicating a possible revival of absentee ballot lawsuits that could lead to increased election litigation. Chief Justice Roberts has raised concerns about the implications of limiting candidate lawsuits around election times. The outcomes of these cases may have far-reaching effects on election integrity and the legitimacy of mail-in voting processes.
