The problem with California is that politics are controlled by San Francisco, Silicon Valley, and Los Angeles proper. There are a great many people in the Central and Northern part of California that are unrepresented due to their lack of population as compared to the metro areas (even though their population is substantial) and many of the people in these unrepresented areas are "conservative" not necessarily my definition of conservative. However, many from those areas are moving away from California for the very reason they have no representation and the state they grew up in is taking freedoms away from them at every turn, and 2nd Amendment freedoms is just one of the many (i.e. delta smelt before farmers for water rights, laws restricting home schooling, energy compliance with what you can and can't do with your home and property, regulating well water on private ground, immigration above safety of citizenry, release of inmates due to fiscal and judicial irrersponsibility, and I could go on and on).
So we must be careful when we say
they did this to themselves (they is much to broad a term for this situation), or they voted these restrictions in, as we could find ourselves in the very same situation with the liberal metropolitan areas of our own states dictating the direction all in the state must go. The last hope for California gun rights is the organization CalGuns, it's size is the only determining factor in rebuffing these draconian laws.
It is true, as my friend just talked with his FFL family member down there recently, that with this new law, the DOJ for California is dragging it's feet establishing the system to permit ammo sales. So until the DOJ gets that established FFL's cannot without breaking the law sell any ammo to individuals. But I'm sure the DOJ has everyone working on that problem...
