As for how states created after California was split would tend to vote, in the short run at least, that would depend on where the lines were drawn and how many such states were created. Since California is currently dominated by liberals, I am hard put to be optimistic that they would permit a net weakening of their national political strength.
Of course, any conservative states created out of California could reasonably expect to prosper after liberation from the immense fiscal drag of the free-spending areas of the state. As in most other liberal states, the fiscal reality of state politics is that conservatives are heavily over taxed in order to finance the projects of their liberal political masters. From that perspective, I easily understand how California's hard-working Germans want to be liberated from supporting their free-spending, layabout Greeks.
That the political balance has tipped HEAVILY
in favor of liberals is a reason why we want
to change things. At one time the state senate
was represented by 1 senator from each county
and the assembly was represented on a population
basis. Now, both houses are based on population.
We would at least like to go back to the old
way so rural counties would have some
representation.
