At the turn of the 20th century, Wisconsin government was rife with corruption. Big business and wealthy plutocrats controlled the politicians and thus controlled the government. They had their puppet politicians pass laws that benefited them regardless of who might be hurt by them.
This high level of corruption gave way to a progressive movement led by Fighting Bob LaFollette. LaFollette, who was a Republican, led the way to clean up the government, enacting laws that returned the government to the control of the people. He led the way to busting trusts, enacting election reforms and creating the Wisconsin Idea. The changes brought on by LaFollette and other progressives have well served the people of Wisconsin for over a 100 years.
