I can easily imagine vulnerable members approaching a corporation or union for support and being told: “We’d love to support you, but we have a rule. We only support candidates who are with us at least 90 percent of the time. Here is our questionnaire with our top 10 concerns. Fill it out.” Millions of campaign dollars now ride on the member’s response. The cause of good government is not served.

What to do? While fundamental campaign finance reform may ultimately require a constitutional amendment, there are less drastic steps we can take to curb the distorting influence of money in politics. Congress should consider ways to lessen the impact of the Citizens United decision through legislation to enhance disclosure requirements, require corporate donors to appear in the political ads they finance and prohibit government contractors or bailout beneficiaries from spending money on political campaigns.

Congress and state legislators should also consider incentives, including public matching funds for smaller contributions, to expand democratic participation and increase the influence of small donors relative to corporations and other special interests.”
