"... Think of what version control software could mean for the Congress [...]. If bills were created under a system where strike-throughs and additions were carefully tracked, the public would know which legislator made which change to a proposed piece of legislation as it made its way through the Capitol.

Best-case scenario, it would shame legislators from inserting language against the public interest and only meant to reward political contributors; at worst, it would make such insertions public and allow the voters to punish the politicians who made them. ..."
