The true answer to your question is that I don't know, just because of the thousands of local jurisdictions we have. I don't know about all of them. I know that at the state level, there is a tendency, in half of the states, if you want to amend the state constitution, to go through a referendum. These types of questions would often be constitutional rather than statutory. It would be normal in half of the states to go through this process. They tend to be the western states. The older states do not have the referendum process for this purpose and they could make these types of decisions just through legislative action.
I'm sorry; there's variance at the state level. It's very decentralized. The Constitution of the U.S. gives very few instructions. It leaves it to the states to decide the manner in which they decide these things.
