March 22 (UPI) -- The U.S. Supreme Court is scheduled to hear Watson vs. Republican Nation Committee, a legal case that could have ramifications on mail-in balloting deadlines in the upcoming mid-term elections, on Monday.

About 30 percent of voters cast their ballots by mail in 2024.

CBS noted that 14 states and the District of Columbia have extended deadlines for counting mail-in ballots that are postmarked by Election Day.

Illinois, for instance, counts ballots received up to two weeks after Election Day, while California has a grace period of seven days.
