As Herbert Hoover picked up the issue of Prohibition to attack Al Smith.
Al Smith suddenly found himself in a predicament.
In the United States, there are two major groups supporting Prohibition.
Puritans and women!
The Puritans might not have the numbers, but they have great prestige and a very radical approach.
The number of women is overwhelming, and Herbert Hoover's speech on ABC could be said to have directly reminded these women of the painful experiences of ten years ago, when their husbands would beat them after drinking.
Before Al Smith could think of a countermeasure, the Puritans had already begun to protest, either by convening meetings internally to denounce Al Smith, with such people having great prestige in the United States.
Or by rallying together and taking to the streets to protest against Al Smith, even though these people might not have much influence, they can create significant momentum.
