Redding residents registered with the Democratic party are being called on to vote in a Primary today for First Selectman. Incumbent Julia Pemberton is seeking a 5th term. She is being challenged by Region 9 Board of Ed member Mike D'Agostino. He says the biggest issue that prompted him to get into the race was the long stall on developing the former Gilbert & Bennett Wire Mill site.  Pemberton has said the delay with redevelopment has been a court case of liens on the property.  Polls are open at Redding Community Center for registered Democrats until 8pm.
