Prohibition of alcohol is an issue that galvanized some of the American public from the 1800s up through the 1950s.

Often the two major parties adopt planks in their platform that co-opt the ideas of the smaller parties in response to public pressure, making the candidates less viable in general elections.Learn more about Political Parties
