Only a few states have state guards, which are like national guard groups that have no connection to the federal government. Most of these are on the east coast in democratic areas because republicans look at them and go: "Why do we have a state guard and a national guard? They do they same thing. If we cut the state guard, we can pass a tax cut!"

However, state guards are perfectly legal. In fact, that is what the 2nd amendment means when it says 'well regulated militia'. Sadly, I don't think California has one.
