Muth was unopposed in the Democratic primary. In the general election, she defeated incumbent RepublicanJohn Rafferty - who had represented the 44th District since 2003 - by a margin of 62,692 to 57,943. Her victory was part of the "blue wave" that increased Democratic and female representation in the Pennsylvania General Assembly and Congressional delegation. Her candidacy was considered a long-shot in many political circles, but her well known tenacity and hard-work, coupled with the fact that she was a working-class candidate and an outsider of the Democratic party establishment won over voters of all political parties as she went on to win what was considered one of the most shocking victories in recent Pennsylvania election history. Her campaign focused on themes such as transparency, integrity, and honest leadership.
Committee Assignments
Muth sits on the following committees in the Senate:
During a budget debate in June of 2019, Senator Muth took the floor and read a letter from a disabled constituent who relies on the PA General Assistance Program. Throughout her reading, Republican Majority LeaderJake Corman of Bellefonte loudly raised a point of order which was not recognized by the president. The Republican-controlled Senate voted against renewing the program 26–24.

Residents and their family members had no idea how many people were dying at the four-story veterans’ home near the Schuylkill River when the . The news was stunning: 26 residents had died in what had clearly become one of the deadliest coronavirus outbreaks in the state. Muth challenged the results of an "independent" investigation in which the state found no wrong doings at the center. In late May 2020, the governor’s Office of General Counsel engaged outside counsel to conduct an independent investigation of the outbreak at the center and the way the home and the state Department of Military and Veterans Affairs addressed the crisis. No details have been released. Muth stated, "I blame a state system that is internally regulated with no guarantee of transparency, from the doctors and the director at the Department of Military and Veterans Affairs to the inspectors and the secretary at the Department of the Health." Muth continued to push for answers and later called on Attorney General Josh Shapiro to investigate the Center. As of July 2020 that investigation is ongoing.
