Analysis of Campaign Finance Laws by State

Campaign finance laws have been put in place to protect our political process from corruption. At the same time, they enable candidates to raise funds for their campaigns and allow funders to support the political candidates of their choice.

Campaign finance laws regulate the source, amounts, and use of contributions in elections, as well as required disclosures. These laws cover individual candidate campaigns, political parties, and donors. They also cover third parties that pay for political advertisements for or against a particular candidate or ballot issue.

What Is a Political Contribution?

A political contribution is:

  • A gift
  • A loan
  • An advance
  • A deposit of money
  • Payment from a third party
  • Forgiveness of a loan
  • Payment of a personal expense or service
  • Transfer of anything of value (or a contract or agreement to do any of the above)

Contributions may only be accepted to influence the outcome of an election, pay off campaign debt, or to pay for expenses associated with an election challenge.

Who Can Make a Contribution to a Candidate?

The following individuals and entities can make a contribution:

  • An individual person: In some states, it matters if that person lives in the state where the candidate will serve in office (see Alaska).
  • Political party committees: In some states, political parties can donate an unlimited amount to a political candidate's campaign fund. In other states, political party donations to individual candidates are capped at the same contribution limit of individuals, or it has a different cap.
  • Corporate contributors: Five states allow unlimited corporate contributions; 22 states prohibit contributions to candidates. The rest set a limit on corporate contributions.
  • Political Action Committees: PACs enable their members to pool their campaign contributions to support a candidate, a ballot initiative, or legislation. Corporations can contribute to a PAC and avoid the restriction on corporate contributions to a political candidate. Thirteen states allow unlimited PAC contributions to a specific candidate; the remainder set a limit.
  • Other contributor categories can include unions, nonprofits, associations, Super PACs, and more.

See the National Conference of State Legislatures (NCSL) for additional information on state limits on contributions to candidates. You can also follow pending legislation on campaign finance at the NCSL website page: 2015 to Present Campaign Finance Legislation Database.

Federal Laws That Have Impacted State Campaign Finance Laws

Federal campaign finance laws regulate finances for presidential and congressional campaigns. State campaign finance laws regulate finances for offices like the governor, state legislators, judges, and other state or local candidates. State laws do not need to match federal laws, as we saw above. But sometimes federal court decisions do influence state laws.

In 2010, the U.S. Supreme Court ruled in Citizens United that the government was prohibited from restricting independent expenditures from corporations, labor unions, and other associations. It impeded their political communication and violated their First Amendment right to free speech.

After this ruling, some states raised or eliminated their contribution limits for corporations, unions, and associations.

Citizens United also led to the creation of Super PACs – groups that can spend on campaigns, issues, and legislation but not candidates.

In 2014, the Supreme Court ruled in McCutcheon v Federal Election Commission that limiting the total amount an individual can contribute violated that donor's First Amendment right. This ruling trickled down to the state level, and some states changed their rules regarding aggregate contribution limits. Some stopped enforcing limits. Wisconsin saw its existing law struck down in court.

What Do State Campaign Finance Laws Cover?

State campaign finance laws vary, but they typically cover such topics as:

  • The requirements for candidacy
  • Contribution limits from individuals, corporations, committees, PACs, etc.
  • Contributions rules for candidates, candidate committees, political parties, ballot initiatives
  • How often candidates and campaigns must report contributions, and what information must be disclosed (see NCLS for state-specific information on disclosure and reporting requirements)
  • Public financing and associated limits to soliciting contributions and expenditures.

Campaign Financial Filing Requirements

Serious candidates — those who have filed and received contributions of a designated amount — are required to:

  • Appoint a campaign committee: The campaign finance committee form will list all the members and a designated filing agent who is authorized to file reports.
  • File a Statement of Economic Interests: This form outlines the candidate's previous year's finances.

Candidates must report their finances to the Secretary of State. The timing of required financial reporting depends upon the amount of contributions a candidate receives and expenditures made.

Reporting could be required annually, monthly, weekly, daily, and/or when candidates receive a major contribution.

Public Financing

Public financing takes two forms: "clean election" programs that offer full funding for a campaign (ME, AZ) and "matching funds" programs that provide a portion of the funds.
