Holding that the Oklahoma’s semiclosed primary system, under which a political party could invite only its own registered members and voters registered as Independents to vote in its primary, did not violate First Amendment right to freedom of political association of political party or registered members of other parties; system imposed only minor burden on associational rights of the state’s citizenry and advanced important regulatory interests in preserving political parties as viable and identifiable interest groups, aiding in parties’ electioneering and party-building efforts, and in preventing party raiding. Clingman v. Beaver, 544 U.S. 581, 125 (2005).

Holding that the purpose of party registration is to provide a minimal demonstration by the voter that he has some commitment to the party in whose primary he wishes to participate. Clingman v. Beaver, 544 U.S. 581, 125 (2005).
