Conservative justices appeared ready to strike down so-called “grace periods” for election officials to count mail-in ballots after Election Day.

A Republican push to limit mail-in ballots in elections is hitting the Supreme Court, and the case could have big implications for the upcoming midterms races.

The U.S. Supreme Court is to hear Monday a legal case that could have ramifications on mail-in balloting deadlines in the upcoming mid-term elections.

The case could impact laws in more than a dozen states.

Conservative justices appeared ready to strike down so-called “grace periods” for election officials to count mail-in ballots after Election Day.

Mississippi's law counts mail-in ballots sent by some voters if they were postmarked on or before, and received up to five business days after, Election Day.

The Supreme Court's conservative majority seemed skeptical of late-arriving ballots. The case could lead to stricter rules in this year's midterm elections.
