Majority of California residents recognize the fact that she is a completely different country from the rest of the states. The Federal Government laws in no way represent the interests and needs of Californians.
"... Governments are instituted among Men, deriving their just powers from the consent of the governed. That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness."
Californians should be deciding issues like air quality, if oil should be drilled off the Californian coast, forest management practices, food safety, taxes, etc.
