The U.S. Supreme Court is scheduled to hear a case on Monday that could have ramifications on mail-in balloting deadlines in the upcoming mid-term elections. The case, Watson vs. Republican Nation Committee, will look at whether extended deadlines for counting mail-in ballots that are postmarked by Election Day violate federal statutes recognizing Election Day as a specific date.

Why it matters

This case is significant as about 30% of voters cast their ballots by mail in 2024. Extended deadlines for counting mail-in ballots have been implemented in 14 states and D.C., but conservative groups argue this increases the risk of fraud. The outcome could disproportionately impact Democrats, who are more likely to vote by mail.

The details

The case will examine whether states can count mail-in ballots received up to two weeks after Election Day, as is the case in Illinois, or have a seven-day grace period like California. Conservative groups argue this 'greater opportunity for and risk of fraud', while Democratic attorneys say eliminating grace periods could strip people of their voting rights due to postal delays.
