If countries outside of the US can manage to run their government without extreme interference of lobbyists, then there is certainly a way for us to do it, too. The problem here isn't "well, how will politicians get accurate information without having to spend loads of time doing research?" It's more an issue of the culture in the US. If we make a shift towards a system more like the one in Germany mentioned above, it will become the cultural norm in the US. The problem is making that shift and breaking our current financially-driven habits.
