Prohibition was repealed the old-fashioned way: 2/3 of Congress (House and Senate) sending it to the State legislatures where 3/4 of the state legislatures voted for its repeal.
Just returned from some sites ... nowhere does it say the people had any input, ie, voting one way or other ... so it’s up to the state legislators to ratify without the peoples voice ....unless through write-in campaigning ....
