Actually, only a few states took actual secession articles to the voters. In most, the legislatures called for the election of delegates to a convention, and those delegates voted secession up or down. In the case of Louisiana, for example, the convention held a specific vote on submitting actual secession to the people, as required by the state constitution, and rejected the idea 84-45.
Either way it was not “chaotic”. The war was chaotic, the secession was not.
