The geographic lines of division today have changed tremendously since the Civil War. The divide is now more rural versus urban rather than north versus south. In the last presidential election rural California was mostly "red" while southern cities were mostly "blue".

California's /land/ was mostly red...in terms of actual people it was 2:1 voting blue:red. Land doesn't vote.

Land does vote in the senate though.
