Portland Maine Campaign Finance Data

2019 Mayoral Election (Tuesday, November 5, 2019)

An OpenMaine Project

About the project

The aim of this project is to make it easier for people to access campaign finance data which otherwise is only obtained by going directly to the City Clerk's office or by obtaining a PDF version of campaign finance contributions via a source like the Portland Press Herald. Our goal is to provide data in an accessible format so that voters and interested parties can freely and easily access it.

Campaign Finance Data

Candidates running for office in Portland, Maine are required to file campaign finance reports with the city 42 days before the election, 11 days before the election, and 42 days after the election. Reports are often filed on paper and the city does not post them to their website until after the election. Further information on reporting requirements can be found in the 2019 Municipal Candidate Guidebook
