Democratic state representative Leslie Acosta was re-elected during the 2016 elections, but later resigned after pleading guilty to charges of embezzlement.[4] A special election for the 197th legislative district took place on March 21.
Republicans nominated Lucinda Little for the seat. Democrats originally nominated health clinic administrator Frederick Ramirez, but a Commonwealth Court ruling declared that Ramirez did not reside in the district and removed him from the ballot.[5] Democrats attempted to replace Ramirez with Philadelphia Parking Authority auditor Emilio Vazquez, but the Court ruled (and the Supreme Court of Pennsylvania confirmed) that the filing deadline had passed, preventing the substitution.[6] Vazquez subsequently ran a write-in campaign, along with Green Party candidate Cheri Honkala.[7]
Following the special election, four elections officers were charged with interference after allegations of duress and voter intimidation were made.[8]
