By Jennifer Learn-Andes jandes@timesleader.com Luzerne County’s electronic voting machines are seen being demonstrated in this file photo. The county’s election bureau will publicly post a complete list of all seats set to appear on the May 18 primary election ballot, likely by the middle of next week. �� Listen to this Luzerne County interim Election Director Andrea Hill urges residents to pay attention to the seats that are up for grabs in the upcoming primary. “If more candidates get on the ballot, it will alleviate the need to process as many write-in votes,” Hill said Wednesday. The tallying of write-in votes is more cumbersome for the county Election Board and election bureau, particularly with now-popular mail voting. Instead of typing write-in selections on electronic ballot marking devices at polling places, mail voters must write them in by hand.
