Actually Mexico only had California from 1821 to 1846, or 25 years. That is less time than it was under Spanish rule. Spain established the Missions starting about 1769. So Spain had it for 56 years. It was "The Republic of California" for about 25 days. Then the USA came in during the Mexican-American War. California became a (free) state in 1850 and has been a US State ever since. So should it revert to Mexico? 25 years versus 160 years? Give the people the vote. We'll let the inhabitants of California vote whether to join Mexico and the inhabitants of Baja California vote whether to become US citizens. How do you think that will turn out? Prior to that time Spain, and England had explored, mapped and tried to lay claim. During the Mexican period Russia tried to establish a claim. 1967 is 42 years ago, just to give the question some perspective. There were about 15000 non-natives in California prior to 1848.
