How does the constitutional amendment process differ from the national to the state level?

Two-thirds of the membership of each chamber of the California State Legislature must propose an amendment, which then goes on a statewide ballot to be ratified or rejected by the state's voters. The state legislature is allowed to propose revisions (not just amendments) to the constitution.

Hope this helps. 

Perhaps the greatest obstacle John F. Kennedy had to overcome to become president was his religious background as an Irish Roman Catholic. Most presidents had been Protestant.
