I don't know for sure. Was there a Gallup poll? I would think most Spanish speakers would prefer Mexican rule. Considering the native American population of California decreased by 85% in the first 40 years of US, I would think native Americans would prefer the Mexicans. Native Americans supported the French in the French and Indian War. and the British in the War for Independence and War of 1812.What made Mexican rule more attractive? Its laissez-faire approach? Couldn't that have been a downside as well due to these regions being largely neglected by the Mexicans?
