HARRISBURG, Pa. (AP) — Voters in three Pennsylvania House districts will choose new state representatives during special elections scheduled for March. A top aide to Republican House Speaker Mike Turzai said Tuesday the March 17 date was chosen to fill seats vacant because the incumbents have been elected to other offices. The seats were most recently held by Rep. Tedd Nesbit of Mercer County, Rep. Gene DiGirolamo of Bucks County and Justin Walsh of Westmoreland County. Nesbit and Walsh were elected in November to become county judges, and DiGirolamo is now a county commissioner. All three are Republicans.
