Answer:
The Anti-Saloon League (ASL) was an effective advocacy group because it was a single issue lobbying group. The ASL was the first modern pressure group in the United States to focus on one issue, prohibition. The ASL was non-partisan, and its members worked with churches to raise resources for the cause. The ASL also used propaganda, religion, and political coercion to make alcohol a wedge issue
in elections.
The ASL was formed in 1893 and became a major force in American politics from 1893 to 1933. The ASL's
goal was to close saloons and dismantle the liquor industry, which it blamed for social and moral problems. The ASL's consistent pressure led to public figures and organizations taking a stand, eventually resulting in the Prohibition Amendment to the United States Constitution.
