(called "Stalwarts") to elect Emanuel Philipp as governor in 1914. The Stalwart counterattack said the Progressives were too haughty, too beholden to experts, too eager to regulate, and too expensive. Economy and budget cutting was their formula. The progressive Wisconsin Idea promoted the use of the University of Wisconsin faculty as intellectual resources for state government, and as guides for local government. It promoted expansion of the university through the UW-Extension system to reach all the state's farming communities. University economics professors John R. Commons and Harold Groves enabled Wisconsin to create the first unemployment compensation program in the United States in 1932. Other Wisconsin Idea scholars at the university generated the plan that became the New Deal's Social Security Act of 1935, with Wisconsin expert Arthur J. Altmeyer playing the key role. The Stalwarts counterattacked by arguing if the university became embedded in the state, then its internal affairs became fair game, especially the faculty preference for advanced research over undergraduate teaching. The Stalwarts controlled the Regents, and their interference in academic freedom outraged the faculty. Historian Frederick Jackson Turner, the most famous professor, quit and went to Harvard. Wisconsin took part in several political extremes in the mid to late 20th century, ranging from the anti-communist crusades of Senator Joseph McCarthy in the 1950s to the radical antiwar protests at UW-Madison that culminated in the Sterling Hall bombing in August 1970.

A series of major protests by union supporters took place that year in protest to the changes, and Walker survived a recall election held the next year, becoming the first governor in United States history to do so. Walker enacted other bills promoting conservative governance, such as a right-to-work law, abortion restrictions, and legislation removing certain gun controls. Walker's administration also made critical changes to Wisconsin's
