While campaigning for a second term as Councilor, Deaglan said, "I firmly believe that the character of our city lies in its people. We must build a community that helps us grow together as neighbors, not apart. I remain confident that together we can build a Portsmouth that works for all of us, and I remain committed to working for you. Please join me.”
