The power to write our tax laws should never depend on the size of a campaign check. Yet billionaires and corporations have extraordinary resources to help elect lawmakers who protect their fortunes, preserve corporate loopholes, and deliver more tax breaks for the rich.

The Supreme Court has spent years tearing down safeguards against billionaire influence. Its 2010 Citizens United decision struck down restrictions on corporate independent election spending. Alongside related decisions, it helped establish the legal framework for unlimited spending through super PACs.

This June, the Court went further, striking down limits on political party spending coordinated with candidates. Those limits helped prevent donors from using large contributions to party committees to get around restrictions on direct candidate contributions.

Then, on October 14, the Court intervened again in a dispute over discounted political advertising ― ruling in favor of the Trump administration, extending lower TV ad rates to party committees and joint fundraising committees, creating a policy that strengthens the influence of wealthy donors.

Working families bear the consequences of a political system that gives wealthy donors so much influence. Our communities need affordable health care, strong public schools, and investments paid for by making billionaires and large corporations pay their fair share. Winning those priorities requires confronting the big money that buys elections and elected officials.

Send a message now demanding that Congress advance a constitutional amendment overturning Citizens United and related decisions, restore congressional and state authority to limit political spending, and protect the voices of everyday voters.
