How One Case Changed Every Election

In 2008, a group called Citizens United made a 90-minute film attacking Hillary Clinton and wanted it on cable before the primaries. Federal law said corporations couldn’t pay for election ads that close to a vote.2

Five justices threw that law out. Spending money to win an election became protected speech. Corporations and the groups they fund can now spend without limit, as long as they don’t coordinate with the campaign.2

Two months later, a lower court used the ruling to create the super PAC.3

Undoing It

How We Undo It

Democracy for All Amendment

Would let Congress and the states set reasonable limits on raising and spending money in elections. The Senate version, S.J.Res. 43, had 36 original cosponsors; the House version, H.J.Res. 121, had 31.89

25 States on Record

American Promise counts 25 states that have formally asked Congress to send an amendment to the states. Ratifying one takes 38.10

A Different Court

The Court overruled its own precedents to decide Citizens United, so a future Court could do the same. For now it is moving the other way, as NRSC v. FEC showed this June.5
