According to a 2018 study in the journal "Public Choice", "Senator John Sherman of Ohio was motivated to introduce an antitrust bill in late 1889 partly as a way of enacting revenge on his political rival, General and former Governor Russell Alger of Michigan, because Sherman believed that Alger personally had cost him the presidential nomination at the 1888 Republican national convention... Sherman was able to pursue his revenge motive by combining it with the broader Republican goals of preserving high tariffs and attacking the trusts."
