RICHMOND, Va. (AP)- A voter advocacy group’s mistake is adding to the challenges of elections officials in Virginia.

The Center for Voter Information in Washington sent mail-in ballot applications with incorrect return addresses to hundreds of thousands of voters in Virginia.

The Virginia Department of Elections said it will immediately forward any such applications to the correct election offices for processing. The group has apologized in a news release, blaming computer errors.

Elections officials say any voter wanting an absentee ballot should apply online through the state’s website.

Some local voter registrars are complaining that the advocacy group means well but is really draining their resources.
