Self-interest is the driving force in human affairs, and it can be relied upon to be present in most circumstances, certainly mundane political decisions. However, good self-interest borders on bad self-interest, greed. The transition from one to the other is seamless and even logical when no constraints apply. Everyone has experienced such a thing in their lives on one level or another, except apparently those who create the legal framework for large donations. "Political donations" have always greased the rails for a donor's political needs. It's the oldest political scandal there is, and updates to that scandal arrive daily. This testimony is smoking gun proof that the system works best for those who can make the best political donations. It's obviously time to try public financing for political campaigns.
