About ODCa - Welcome!


Welcome to Open Disclosure (ODCa)! ODCa is California’s first online source for local campaign finance data from city and counties across the state. ODCa combines campaign finance data from local cities and counties to create a comprehensive picture about who is influencing elections state-wide. We track contributions and expenditures to candidates and ballot measures at the local level. We hope to be ready for the 2016 Election Season.

Our site in progress can be seen at disclosure.caciviclab.org
Mock-ups are posted on GitHub version 16 here

Help wanted


Open Disclosure is a group of volunteer civic hackers passionate about open data, transparency and shining light on the funding that fuels California’s electoral campaigns. We're currently working with Code for America Brigades and volunteers across California to create a website that any community in the state can use to make their campaign finance data transparent and easy to understand.

We're looking for help across the board, technical and non-technical background. Let us know if you can help, or look through our Github issues for something interesting.
