In his campaign Facebook page,John Green touts an endorsement for his Republican candidacy for Kootenai County sheriff by controversial "Sheriff" Richard Mack. Mack, who served as sheriff in Graham County, Ariz., from 1988 to 1996, is founder of the Constitutional Sheriffs and Peace Officers Association. Also, he is a member of the Oath Keepers organization Green writes on his campaign site: "I am happy to announce that I have, again, been endorsed By Sheriff Richard Mack, in my campaign for Kootenai County Sheriff! I'm honored by Sheriff Mack's endorsement, confidence and most importantly, his friendship!" Green is running for a second time against incumbent Ben Wolfinger in the Republican primary for Kootenai County sheriff.
Question: Why would the endorsement of a former sheriff from Arizona be important to someone running for sheriff in Kootenai County, Idaho?
