An affiliation of electors satisfying the requirements of this subsection shall be subject to the provisions of ORS 248.007 on the date the Secretary of State determines the registration requirements are satisfied.

(3) After an affiliation of electors becomes a major political party under subsection (1) of this section, in order to maintain status as a major political party subject to ORS 248.007, the party must satisfy the registration requirement of subsection (1) of this section not later than the 275th day before each primary election.

(4) An affiliation of electors ceases to be a major political party if the registration requirements of subsection (1) of this section are not satisfied by the 275th day before each primary election. The affiliation of electors ceases to be a major political party on the date the Secretary of State determines that the registration requirement is not satisfied.

(5) When an affiliation of electors has not satisfied the registration requirement of subsection (1) of this section for the first time, at the request of a representative of the affiliation of electors, the Secretary of State shall determine not less than once each month whether at least five percent of the number of eligible electors registered in this state are registered as members of the party. After an affiliation of electors has qualified as a major political party, the Secretary of State shall determine on the 274th day before each primary election whether the major political party has satisfied the registration requirements described in subsection (3) of this section.
