Tracie Cone, former owner and editor of the Hollister Pinnacle newspaper, will be in a run-off in November for a seat on the San Benito County Board of Supervisors against incumbent Reb Monaco. Neither candidate in a three-way race received more than 50 percent, which was necessary to win the seat Tuesday. Cone, in her first run for elected office, came within 41 votes of the incumbent, not including absentee ballots which still must be counted. Monaco had 652 votes (36.53%), Cohn had 611 (34.23%) and John Hodges had 520 (29.13%). Cone, 48, quit her job as a Mercury News staff writer in 1999 and bought The Pinnacle in Hollister. She sold it in 2004 to MainStreet Media, which has acquired other nearby papers including the Gilroy Dispatch. She stayed on for a year as publisher before a family health crisis caused her to quit. She said that when the health issue cleared up, she decided to run. The run-off is Nov. 7.
