It would appear that the laws on rights to vote are scattered all over the states...
Restoring Your Right to Vote
California
Issued December, 2000 The right to vote is an important civil right in a democracy as well as a civic responsibility, and yet many persons who have been convicted of a crime do not know whether they are eligible to vote. For both federal and state elections, the right to vote is controlled by the law of the state in which you live. Some states restrict the right to vote for persons who have been convicted of a crime. This pamphlet is intended to help you determine whether you are eligible to vote in the state in which you live, and if so, what steps you must take to be permitted to vote.
