In a surprising upset, Democrat Gilman Shattuck defeated former Hillsborough County Sheriff and Republican Walter Morse 669 to 601 on June 14, 2005.
In Cheshire District 3, consisting of the five wards of Keene, Stephanie Sinclair left her seat in mid-spring 2005 because she moved out of New Hampshire.
The opening was filled on October 14, 2005, by Keene City Councilman Chris Coates, who received 250 votes while running unopposed.
On City Election Day, 2005 (November 8), Democrat Jean Jeudy defeated Republican Rob Fremeau, protecting the party's seat after the departure of Firefighter's Union President William Clayton in a special election in Hillsborough District 10, the State Representative district of Manchester's Ward 3.
The election was largely overshadowed by the simultaneous mayoral race, where Frank Guinta upset incumbent Bob Baines.
