The Democratic Party of Virginia has filed a lawsuit contending that hundreds of thousands of mail-in ballots could be caught up in the glacially-paced USPS mail delivery system, threatening to disenfranchise masses of voters and impact the commonwealth's tight gubernatorial race.

Last week, the party filed a lawsuit claiming that as many as 300,000 Virginians intend to cast their ballots in Tuesday's critical election by mail, but local USPS branches have failed to deliver ballots in time for voters to fill them out and return them by the deadline.

"Thousands of absentee ballots currently sit at postal facilities throughout the Commonwealth, unprocessed for weeks on end," the suit alleges, according to The Washington Times.
