[Idaho Statutes Title 34 Chapter 1. 34-102.]

19 May 2023 Idaho Democratic Party post draft plan with the disclaimer: "On March 30th, Governor Little signed HB 138, which moved Idaho's Presidential Primary back to May. Due to an issue in the bill Idaho’s Primary has mistakenly been eliminated altogether. Due to this the Idaho Dems have written a caucus plan for the 2024 delegate election. It is our hope that the legislature will fix this issue. Due to this this plan is highly likely to change."
