In Colorado, for example, the rules for this primary process have been in place since 1912.

According to thegreenpapers.com, regarding Colorado:

21 August 2015: The Republican Executive Committee votes to cancel the traditional Presidential preference Poll at the Precinct Caucuses.

Apparently the rules have changed since 1912.
