California seems to be stricter than many states but it's not just political purposes (which I'm not sure how that is "better" anyway):
In California:
Candidates, parties, ballot measure committees, and to any person for election, scholarly, journalistic, or political purposes, or for governmental purposes, as determined by the Secretary of State. All voter information is confidential except for those listed above that may request lists.
