Ask HN: Examples of successful Open Source political projects

For the last 10 years or so I have invested quite a lot of my hobby time into OSS projects (primarily PouchDB) however recently have found myself wanting to invest my time and skills into more directly ethical tech.

More specifically I am interested in contributing to a specific campaign (Scottish Independence) and while I have a fair amount of experience in building OS projects I have very little experience in politics. I have been finding it hard to think of new projects or even find any examples of projects in this space. I have been reaching out to politically minded people that may have ideas or could possible use help but still have found little to go on.

Has anyone else looked to make this jump, seen good crossover projects of OSS and politics, have any advice (or even ideas for projects!)?
