There could be new metropolisis in the central valley and mojave dessert between LA and LV. In N.Cal Sacramento, could merge with Stockton, Modesto, and maybe the Bay Area into a giant metropolis. There will be a high speed rail connecting the major cities. Demographically LA, and much of Socal and the central valley will be Latino, and the north and south may split. Politically its hard to say the fastest growing political group are independents, but more poor people and renters could lead to socialism, and a threat to Prop.13. LA will become a dense third world city like Mexico City or Sao Paulo. San Francisco will stay similar in size but become much more exclusive.
