Just stumbled on a github repo where a politican released his legislation for public comment on a version controlled website (Source: http://bit.ly/political-sites)
I think this does bring into mind an interested website (say hypothetically this website is called https://git.law). Perhaps there is a website where different parties can submit their preferred legislation draft and it will be diffed against the current law draft.
But the public would also be able to switch between different parties (if those parties have submitted their draft) and compare wording. (Or track the changes over time in an easy to see manner like https://github.com/BenKallos/legislation/commits/master )
Most importantly for usage with current social media landscape. You would be able to share these wordings to the public as a meme-able image perhaps on facebook?
Ideally this would be baked into our government as a public service.
