The bad news is that many Californians will leave- the ones who have the means. They will settle in other states and mess up elections there, too, spreading the contagion. Saw this happen in MA years ago when it was called "Taxachussetts"; many fled to New Hampshire then started running for office, adding all the stupid taxes that drove them out of MA. Tax-happy people don't belong in the US, but we won't be the US much longer even if we retain the name, flag and other stuff. Once we operate like France, the dream of freedom is over.
So the Liberal elite increase taxes too much for their own comfort, then leave and do it to other people.
