How did state-level reformers try to limit corruption and the influence of big business?

State-level reformers sought to limit corruption and the influence of big business primarily through measures such as campaign finance reform, which aimed to reduce the power of money in politics. They also advocated for transparency in government operations and the implementation of direct democracy tools, like initiatives and referendums, to empower voters. Additionally, the establishment of regulatory agencies was intended to oversee industries and curb monopolistic practices. These efforts collectively aimed to promote accountability and ensure that government served the public interest over corporate interests.
