Rhynhart defeated incumbent Alan Butkovitz by receiving almost 58% of the vote with 71% of precincts reported.
Butkovitz, the three-term incumbent, received the endorsement of the Philadelphia Democratic Party and was viewed as the favorite in the race. Rhynhart’s endorsements included former Gov. Ed Rendell and the Philadelphia Inquirer.
Rhynhart will face GOP nominee, Mike Tomlinson, who ran unopposed today, in the November general election.
