SEATTLE (AP) — As midterm voting approaches, Republican activists in Washington are organizing surveillance of ballot drop boxes, generating complaints and concern from some elections officials. Signs were posted near ballot boxes in Seattle-area locations over the weekend. They had red letters warning the boxes are “Under Surveillance” and stating that accepting money “for harvesting or depositing ballots” may violate federal law. A scannable code on the signs pointed to a section of the King County Republican Party website with a form encouraging people to submit “election incident” reports, including photos and video. The signs raised concerns about possible intimidation. King County Elections has notified the County Prosecutor’s Office “to check on the legality” of the effort.
