The NSL lost much of its political influence after two incidents in 1918. One incident happened in April 1918, when McElroy accused practically every citizen in
Wisconsin of
treason. McElroy was addressing some
University of Wisconsin army junior cadets in the rain on the college's campus. The acoustics made it difficult to hear him, and the wet cadets fidgeted throughout his speech. McElroy grew increasingly angry as he spoke, convinced the cadets were ignoring him. Finally, McElroy, whether in exasperation or because truly believed so, accused the students and the university's faculty of treason. However, since no one could hear him, there was no response to his statement. McElroy then broadened his accusation to include the chief justice of the
Wisconsin Supreme Court, who was also in attendance, and the entire population of the state of disloyalty as well. To make matters worse, McElroy published those accusations in a number of newspaper articles. When word of McElroy's statements were made known, the public and the press turned on the NSL and accused it of
xenophobia and
fanaticism. Many mainstream supporters of the League, unaware of the
jingoistic tendencies of some of the more senior members of the organization's inner circle, quit in protest. The other incident involved a massive political operation in the 1918 midterm elections. The League formed the first known
political action committee in the United States and spent more than $100,000 to defeat US representatives who opposed its policies. The NSL established a rating system to analyze a variety of congressional votes on preparedness measures that it considered critical. However, many of the votes seemed to have little to do with national defense or ignored the complexities of congressional voting, which often involved
parliamentary procedure,
up-or-down voting, the
amendment process,
logrolling and agenda setting strategies. Many members of Congress who were for higher defense spending often scored quite low on the NSL's rating system. That did not appear to concern the League, which directed mass mailings and vituperative press campaigns against those members of Congress. The campaign appeared to have an effect, as a number of important members of Congress went down to defeat, and the Democrats lost control of the House. During the
lame duck session of Congress after the election, the Democrats sought to expose the practices of the NSL.
U.S. House Speaker Champ Clark appointed a special investigative
committee to investigate the League's actions. Not surprisingly, most of the committee's members had suffered the wrath of the League. The committee found that the NSL had violated the
Federal Corrupt Practices Act. Bullard closed the League in 1942. ==References==
