California state government is dominated in many ways by interest groups that spend tens of millions of dollars each election cycle supporting and opposing candidates and ballot measures. These interest groups include corporations, professional associations, and labor unions. In recent decades, labor unions—especially public employee unions—have greatly expanded their political spending and influence in the state. This influence is controversial, in part, because it is based on a system whereby unions amass political funds by deducting money from their members’ paychecks, whether individual workers like it or not. Proposition 32 seeks to prohibit this practice, while also prohibiting other organizations, including corporations, from deducting their employees’ salary or wages for political purposes.
