The proposition seeks to repeal the 1988 ban on public funding of elections in California. If passed, it would not mandate public financing but would permit state and local governments to create such programs on a case-by-case basis.

Under Proposition 4, decision-makers, with public backing, would have the authority to set spending limits, eligibility requirements, and the structure for matching funds. This approach is intended to give voters more choices in elections by lessening the reliance on private wealth.

Supporters argue that the current system makes it difficult for candidates without significant financial backing to compete. They point to examples in other states and cities, such as New York City's matching funds program, which they believe have successfully minimized the impact of private wealth in politics.
