Answer:
open primary
Explanation:
An open primary is a primary election where a voter does not have to officially belong to any political party to vote during the election. The person can also decide to form affiliation with any other party of his or her choice [different from the one he or she already belongs to] on the day of the primary election. This system has been used in Califonia and Washington respectively and voters in those occasions were not tied to any partisan affiliations.
