Political Law

Thorough Representation in Campaign Finance, Ethics & Election Law

Campaign finance laws are complex and alien to those who do not encounter them every day; in fact, some judges have compared their complexity to that of tax laws. Participation in the political process, however, is often a necessity in order for the voice of your business, trade association, labor organization or nonprofit to be heard. Recognizing these realities, Winthrop & Weinstine, P.A., has assembled a team with experience working in the public arena, from the legislative process to ballot questions to political campaigns.

Winthrop & Weinstine's Political Law practice group represents a broad range of clients in navigating Minnesota's complex campaign finance laws as well as the federal campaign finance law and the tax laws that affect how these activities are conducted. Our clients include businesses, trade associations, banks, labor unions, nonprofit political committees, Indian tribes, political party units and candidates for public office, both federal and state.

Winthrop & Weinstine's Political Law practice group represent clients before the Minnesota Campaign Finance and Public Disclosure Board and the Federal Elections Commission. Our Legislative and Regulatory Practice group effectively advocates on behalf of our clients regarding proposed changes to campaign finance and election laws and regulations.

We provide campaign finance, ethics and election law representation in all areas, including:
  • Formation and application for tax exempt status of political entities
  • Formation and termination of political action committees (PAC)
  • Reporting and administration requirements for all types of regulated political organizations
  • Permissible corporate political activity
  • Contribution and expenditure limitations
  • Constitutional analysis and litigation of campaign finance statutes and regulations
  • Issues relating to independent expenditures, issue advocacy and “soft money”
  • Ballot initiatives
  • Judicial elections
  • Enforcement proceedings, from administrative actions to litigation

We also provide representation on lobbying and ethics law issues, including how to register and report as a lobbyist, regulation of gifts to public officials as well as conflict of interest and other laws applicable to elected officials.
