PRINCETON — Bureau County Sheriff John Thompson has announced he will not seek re-election in November 2014.

Thompson, a Democrat from Ladd, is serving his third term in office, having been first elected sheriff in November 2002 when he defeated incumbent sheriff Bill Rosenow, a Republican from Sheffield.

On Friday, Thompson said he decided not to seek re-election for personal reasons in the sense that he has developed opinions about government and its methodologies which makes it difficult to continue as sheriff. He believes if he can’t affect enough change as sheriff, then he should get out.
