Fernandina Beach Rotary Club recently welcomed Nassau County Supervisor of Elections Vicki Cannon. Cannon updated the club on the upcoming primaries, particularly the Presidential Preference Primary slated for March 15. Cannon said preference primaries always present special challenges because many voters don't understand that they can only vote for candidates in their registered party. She added that state primary elections will take place in August, followed by the presidential election in November, making 2016 a busy year for her office.
