Starting in the 1890s, the middle class urban Progressive movement became influential in the region (as it was in other regions), with Wisconsin a major center. Under the La Follettes Wisconsin fought against the GOP bosses and for efficiency, modernization, and the use of experts to solve social, economic, and political problems. Theodore Roosevelt's 1912 Progressive Party had the best showing in this region; carrying the states of Michigan, Minnesota, and South Dakota. In 1924, La Follette, Sr.'s 1924 Progressive Party did well in the region, but only carried his home base of Wisconsin.
