Idaho’s first presidential primaries were held in 1976. Ever since, Idaho presidential primaries have been in late May, and were simultaneous with the primary for other office. However, in 2012, the state canceled the presidential primaries because both major parties decided to use caucuses instead.

Now the Idaho Senate State Affairs Committee has introduced SB 1049, to hold a presidential primary on the second Tuesday of March, which would be just a presidential primary, not a primary for other office. The bill would not change the May primary date for office other than president. Thanks to Josh Putnam for this news.
