Since Citizens United, as we’ve noted, corporations have been taking advantage of their permission slip to spend unlimited amounts on elections. Now Bill de Blasio, the public advocate for the City of New York, is making it easier to track which corporations are getting involved in politics.

This week, de Blasio launched a website that breaks major corporations into three categories: those that have pledged to stay out of politics, those that have not pledged to stay out of politics, and those prepared (like Target) to spend money in politics. He also makes it easy for web surfers to contact corporations and encourage them not to spend on elections.

De Blasio’s public spirited website is a great tool, but citizens shouldn’t be expected to spend every election monitoring corporate machinations. Ultimately, we need a constitutional amendment to reverse Citizens United. That’s why we’re asking all federal elected officials and candidates to sign our pledge to support an amendment. Has your representative signed the pledge?
