During an appearance on Current TV's Viewpoint, Ben and Jerry’s co-founder Ben Cohen explained the rationale behind his Stamp Stampede campaign.

"I think that over two-thirds of all Americans -- that's Republicans, Democrats, Independents -- all agree that money in politics is destroying our democracy," he said. "Neither party has done anything about it. Clearly what’s needed is a constitutional amendment to overturn the rulings that money is free speech and corporations are people."

The campaign urges people to stamp phrases like "corporations are not people", "money is not free speech", and "not to be used for bribing politicians" on dollar bills.

"The idea is that if you have more and more people that are stamping these things, it helps spread the movement — it’s monetary jiu jitsu."

The Supreme Court’s 2010 decision in Citizens United v. Federal Election Commission held that limits on outside campaign spending by corporations and unions violated the First Amendment, because political spending was a form of speech.

The ruling paved the way for Super PACs, which can receive unlimited sums of money to influence elections as long as they do not coordinate with a candidate’s campaign. Super PACs have spent $272 million in 2012 so far.
