San Diego is next to an ocean, much closer than Phoenix for desalination.....
Also, CA has massive runoff from the Sierra Nevada they can tap into, and have rights on. Phoenix has neither of these, is increasingly drawing down into their groundwater. Oh, and that wonderful CO river? What happens as Colorado's population continues to grow? They have rights on that water...... Including Denver if they suddenly decide they want in on it too.
