HARRISBURG, Pa. (AP) — Voters in a western Pennsylvania state House district will be filling a vacancy next week and deciding which party will hold the speakership. The district at stake in a special election on Tuesday includes towns along the Mon Valley steel region southeast of Pittsburgh. The race pits McKeesport Police Officer Dan Goughnour, the Democrat, against longtime volunteer firefighter and current White Oak Borough Council President Chuck Davis, the Republican. Since Democratic state Rep. Matt Gergely died in January, the House has been deadlocked at 101 to 101. Democrats hope to keep the seat and maintain Democratic Speaker Joanna McClinton as the chamber’s presiding officer.
