I had hoped that the current presidential campaign debates might educate the public as to what is really involved in the ongoing controversy over campaign financing.

Unfortunately, the media, which are not at all reluctant to act in their own self-interest, have succeeded in equating reform in the public mind with further restrictions on just about everyone else's freedom of political speech.

Given the difficulty of resisting such temptations over the longer run, a proper concern for the welfare of congressional souls may well be the ultimate argument in favor of term limitations.

The kind of corruption the media talk about, the kind the Supreme Court was concerned about, involves the putative sale of votes in exchange for campaign contributions.

They may then be willing to cast principled votes based on an educated understanding of the public interest in the face of polls suggesting that the public itself may have quite a different understanding of where its interest lies.

In rendering its decision in our case, the Supreme Court equated money with speech because these days it takes the first to make yourself heard.

This source of corruption, alas, is inherent in the democratic system itself, and it can only be controlled, if at all, by finding ways to encourage legislators to subordinate ambition to principle.
