Any provisions of this Title which pertain particularly to any election or to the general election or to the primary election for the general election shall apply to the primary election for delegates and alternates to national conventions insofar as they are not inconsistent with the special provisions of this Title pertaining to the primary election for delegates and alternates to national conventions.

Notwithstanding any provision of this Title, national and State party rules shall govern the selection of delegates and alternates to national party conventions, provided the State chairman of the political party notifies the Secretary of State prior to March 1 of the year in which delegates and alternates are elected of the applicable party rules governing the delegate selection process. The Secretary of State shall notify the county clerks prior to April 1 of the year in which delegates and alternates are elected of the applicable party rules, if any, which apply to matters within their jurisdiction. Pursuant to this section, the Secretary of State shall issue to the county clerks uniform regulations governing the delegate selection process.
