In 2010 the United States Supreme Court voted 5-4 in the case Citizens United v. Federal Election Commission. The ruling said that freedom of speech prohibited the government from restricting independent political expenditures by a nonprofit corporation.
The principles articulated by the Supreme Court in the case have also been extended to for-profit corporations, labor unions and other associations.
The case of Citizens United allows for dark money, the funds given to nonprofit organizations that can receive unlimited donations from corporations, individuals, and unions, and spend funds to influence elections, but are not required to disclose their donors.
The Supreme Court’s decisions in Citizens United and other cases opened the gates to a flood of billions of dollars that threatens to undermine our democracy.
What we need now is a constitutional amendment to overturn Citizens United.
