Literally he is correct, but the point is irrelevant. I don't think many people think that state governments are going to organize militias as a bulwark against the Federal government. Even in the Civil War the Confederate States needed a federal army to fight the Union. But the 2nd Amendment doesn't address that anyway. When it talks about a militia being vital to a free state, it means an unorganized militia of all citizens, not organized state militias. And the idea that armed citizens are a counter to a potential dictatorial government is fortunately something that at least a significant portion of Americans still believe.
Beg do differ here... The US Civil War of 1861-1865 was fought largely by units which were privately raised at a state level. This was, perhaps the last war in our history where regiments levied by individual states were a prominent factor...
