Maybe we should have a look at what practices are already in the law-making procedures

Most Political Science curricula have senior and graduate level "policy analysis" courses that provide a good basis for appropriate analysis of the impact of laws. Lots of congressional staffers have this background. But successful politicians, (ones who have won more than one election), usually learn quickly when to base votes on rational policy and when to base them on receiving sufficient contributions to win the next election. The conservatives believe this is right and proper. The liberals accept that this is what they have to do to survive.
