Help With Large Data Sets

MapLight’s contribution search allows you to download tables of contributions up to 1 million records in size. For larger data sets, you can download data from the FEC.

You can also contact us to let us know what you are looking for. Our staff availability is limited. We may not be able to assist with every custom data request, but we will respond to every request and use your feedback to inform decisions about how to improve our search.
