"It is important to note that the decision does not affect McCain-Feingold’s soft money ban, which will continue to prevent corporate contributions to the political parties from corrupting the political process. But this decision was a terrible mistake. Presented with a relatively narrow legal issue, the Supreme Court chose to roll back laws that have limited the role of corporate money in federal elections since Teddy Roosevelt was president. Ignoring important principles of judicial restraint and respect for precedent, the Court has given corporate money a breathtaking new role in federal campaigns. Just six years ago, the Court said that the prohibition on corporations and unions dipping into their treasuries to influence campaigns was ‘firmly embedded in our law.’ Yet this Court has just upended that prohibition, and a century's worth of campaign finance law designed to stem corruption in government. The American people will pay dearly for this decision when, more than ever, their voices are drowned out by corporate spending in our federal elections. In the coming weeks, I will work with my colleagues to pass legislation restoring as many of the critical restraints on corporate control of our elections as possible."
Update: AP: Obama promises 'forceful response' to Supreme Court ruling on campaign finance.

The Supreme Court's decision [pdf] on the issues of 'corporate personhood' and campaign dollars presented in Citizens United v. FEC hands unprecedented power to big business, and may provoke the most drastic shift in American politics in more than a decade.
