Redding's First Selectman could face a primary in her bid for another term.  A Region 9 Board of Education member is looking to unseat Democratic incumbent  Julia Pemberton.  Mike D’Agostino plans to try to primary, saying Redding is at a crossroads.  Pemberton, an eight-year incumbent, ran unopposed in her last two races.  D’Agostino needs 122 signatures of registered Democrats in Redding to qualify for a primary, which would take place on September 14th.  The Redding Democratic Town Committee endorsed Pemberton for a 5th term, while the Republicans this week chose John Shaban, who most recently was a state representative, for First Selectman.  Incumbent Selectman Michael Thompson gained the backing of the party to seek another term.
