Open Disclosure California provides transparent, non-partisan campaign contribution and expenditure data in an accessible and easy to understand format. We hope this site will engage the voting public and raise awareness and accountability. Ultimately, this is one step toward shifting politics into a movement of civic engagement and ultimate citizen action.


Welcome! We are a coalition of brigades, all volunteers from the California. We would love to get help from folks across the state to help us in building a database of campaign finance data for local jurisdictions across the state. is one piece of the ODCA project. We try to keep our project page up to date with all the information about how we work and where to get looped in.

Please see for more information.

$ nvm install && nvm use # To get on the right node version
$ make setup

Follow the instructions under Finance disclosures.

Finance disclosures

The process of downloading, converting, and calculating the reported financial disclosures is handled by disclosure-backend-static. To get the finance data into this project, we use gulp.js to copy the files over and do some light transformations on their file paths.

If you have thoughts on how this could be improved, let us know!

Update the finance data

In order to get the latest finance data, first clone disclosure-backend-static as a sibling to this project's directory. It is important that the disclosure-backend-static project is cloned to the correct path (../disclosure-backend-static) which is hardcoded in the gulpfile (pull requests welcome).

Then you can run the pull-finance task.

$ make pull-finance

Now rebuild your site with the finance data.

$ make serve


This site is deployed by a scheduled CI task twice daily. It clones the disclosure-backend-static repo and pulls in the finance data before doing a build. Merges to the master branch will also trigger a deploy.

The site is hosted on GitHub Pages. The deploy consists of a force push of the _site directory to the gh-pages branch done by _bin/
