The Supreme Court reaffirmed its Citizens United ruling Tuesday, allowing businesses and labor unions to spend unlimited funds on election campaigns.
The court's controversial ruling was initially made in 2010 in favor of those who say the First Amendment gives organizations the right to spend as much money as they want to support or defeat a candidate.
Tuesday's news means the political action committees, known as "super PACs," sprouting across the country can continued. The groups have already spent tens of millions of dollars on the 2012 presidential campaign season.
Super PACs became popular thanks to well-known comedian Stephen Colbert who, in 2011, requested that the Federal Election Commission recognize his "Americans for a Better Tomorrow, Tomorrow" group.
Through his "Colbert Report" show, Colbert then encouraged viewers to make their own super PACs, raising and spending money to support whatever cause they saw fit.
The groups aren't endorsed by any candidate and anyone can apply to start a super PAC.
Many of the campaign ads now on television were developed from super PAC funding.
Following the Supreme Court decision, advocates of deregulation are also expected to push for lessening limits on direct contributions to candidates and other campaign money rules.
