Residents in three Arlington voting precincts have received erroneous voter cards from the county.

With four weeks to go until Election Day, voters in the Crystal City, Wilson (Rosslyn area) and Abingdon (Fairlington) precincts were sent cards that incorrectly listed the Lyon Park Community Center as their voting location, Arlington County Registrar Linda Lindberg confirmed to ARLnow.com.

Those who live in the Abingdon precinct also received an erroneous flyer, intended for Wilson precinct voters. Wilson and Crystal City voters received the correct flyer.

“Our mailroom sent cards to the correct voters but pulled incorrect precinct data,” said Lindberg. “They are [resending] with a letter of apology from me. I personally proofed the new cards so I know they are correct.”

“The County mailroom has taken full responsibility for the error and are working to get the correct information out to voters as soon as possible,” Lindberg added.

Update at 1:50 p.m. — The Washington Post reports that about 9,000 Arlington voters received mailings with incorrect information. That number was not immediately available from officials this morning.
