The Judges
Idaho has a District Court for the judicial district and a Magistrate Court. District judges are elected in district-wide nonpartisan elections; Magistrate judges are appointed by a district magistrates commission and then face a retention election. Both are state judicial officers, not county officials. Madison County's Courts department page does not publish judges' names.

Notes on the record
- Commissioners and elected officials confirmed on the county's Elected Officials page: Brent Mendenhall (District 1), Dustin Parkinson (District 2), Todd Smith (District 3); also Assessor Shawn Boice, Clerk Kim Muir, Coroner Sam Butikofer, Prosecuting Attorney Rob Wood, Treasurer Angie Moffat — https://www.madisoncountyid.gov/county_government/elected_officials.php.
- The Detention page (madisonsheriff.com/sections/detention/) links to PREA annual audit reports for 2017–2020; the 2018 report was opened directly and confirmed as a real PDF. The Inmate Telephone Services page discloses a $1.25 voicemail fee (Telmate) but no other rate schedule.
- The county publishes multi-year budget PDFs (e.g. budget24-26.pdf, a 108-page document) at https://www.madisoncountyid.gov/county_government/county_budget/index.php, but the PDF checked appears to be a scanned/image document with no extractable text, so a detention-specific budget line could not be confirmed and 'budget' is recorded as no.
- Board of County Commissioners (three-member, elected by district)
These three offices decide who sits in a cell in Madison County and what it costs the people who live here. Nationally, almost 77% of the people who died in local jails in 2019 had not been convicted of anything, and suicide was the leading single cause of those deaths (Bureau of Justice Statistics, Mortality in Local Jails, 2000–2019).
How much is your sheriff — and your judge — costing you?

The sheriff who runs this jail is elected. So are the commissioners who pay for it.
