There is rarely a single person behind changes though. You would have to show a list showing the person who proposed it, the people who requested changes to it and the people who voted for it.
Quite a few people are involved in that. Clerks, lobbyists, lawyers, etc.
Even the reading of the laws that lawmakers vote on is outsourced. (Ie lawmakers often don't read what they vote on.)
You can even have multiple protected branches where "policy makers" merge the work from their lawyer.
