According to this page on the Northfield LWV site:
There will be a special election for the Northfield City Council at-large position vacated by Noah Cashman on the general election ballot in November. The filing period is August 26-September 9. The term of office will run through December 2010 to fill out Mr. Cashman’s original term of office.
This position will be not be included in the primary election (Sept. 9) due to the timing of the filing period. Anyone who might have been considering filing for City Council earlier, but didn’t, now has a second opportunity. It will be too late for anyone who loses in the primary election to file for this seat.
On Monday, August 18, the City Council appointed Dixon Bond to fill this vacancy, to serve for the period of time from August 18 to December 31, 2008.
