In a very tight race, a Penn State professor has won the Democratic primary for the 12th Congressional district.
Democrat Marc Friedenberg beat Judy Herschel by 223 votes, according to unofficial results Wednesday afternoon.
He said his win in the primary came from work by volunteers — getting results in places they put the effort.
Now, he has his eye on the general election where he will face Republican incumbent Tom Marino.
Marino beat challenger Doug McLinko, winning 67 percent of the vote.
