The problem is not "Liberal Californians" per se, it is the corruption that has followed them. Legislative competition in California came to an end as Liberals were elected to the State Legislature and proceeded to re-district California Conservatives right out of office. California has historically been 1-2% within Liberal/Conservative political parity. It's largely a rural state. California is the world's fifth largest supplier of food and agriculture commodities, more than 23 other US states put together. Farmers and farm workers tend to be conservative on many fronts, and they tend to vote in opposition to those in "The City". If the corruption in California can ever be addressed you will again see normal political trends there.
