History of Political Parties That Have Adopted Party Rules Regarding No Party Preference Voters

Since January 1, 2001, California has had a "modified" closed primary system that permits "no party preference" (formally known as "decline-to-state") voters to participate in a party's primary election if authorized by the individual party's rules and duly noticed to the Secretary of State. If authorized by a party, no party preference voters would be allowed to vote for the office of U.S. President for that party.

Listed below is the history of the political parties who adopted a party rule permitting no party preference voters to request a party ballot in recent primary elections for partisan offices.
