Butler County is located north of Pittsburgh and has about 150,000 registered voters, said Sheasley, who said the county is “pulling out all the stops” to make sure those impacted by the issue are able to vote. County officials said in a press release Thursday that they sent out about 40,000 ballots and have had 21,300 returned so far, but it’s unclear how many voters have received ballots but simply haven’t returned them yet.There’s no pile of ballots that have been taken from the Butler County election committee that are sitting around,” Bugar told CNN. “There’s no record or indication that they entered the mail stream. There’s paperwork that goes along with it.”
