Richard Briffault in the Atlantic:

Given the current Supreme Court’s unyielding resistance to campaign spending limits, can anything be done to reduce the power of mega-donors over elections and, ultimately, over government itself? Yes. We can create an alternative system of small-donor democracy fueled by small contributions from ordinary citizens and reinforced by public matching funds. Although the Supreme Court will not allow big money to be limited, the addiction of elected officials to large donations can be controlled, if not completely cured, by making another, more “small-d” democratic source of funds available to them — the small contributions of millions of non-wealthy voters.
