Hmm first clue, duplicate registrations…
Check it out:

Virginia Voters Alliance, an election integrity group, has called attention to the surprising amount of duplicate voter registrations in Maryland and Virginia, challenging the view that voter fraud is nonexistent, Watchdog reports.

According to the Virginia Voters Alliance (VVA), the state has decided to term these as inactive voters, meaning that they join the total of 43,896 Virginia and Maryland voters who are eligible to vote up until 2019.

As state officials have taken little action, Fairfax General Registrar Cameron Quinn has announced she intends to step in, although since there are an estimated 14,646 duplicate registrations, it’s a race to the clock to remove them before the voter database freezes 60 days before a general election.
