There is a growing national movement to establish a 28th Amendment to the constitution of the United States to address the issue of unlimited corporate spending in elections, although the groups working on the issue diverge on what exactly the amendment should say.

One national coalition called Move to Amend (MTA) is led by David Cobb. A Green Party candidate for president in 2006, Cobb has been touring the country calling for a constitutional amendment to “clearly establish that money is not speech, a corporation is not a person, all corporations are subject to regulation, all campaign contributions will be disclosed, and (that) allows for no loopholes,” according to the MTA website.

But passing a constitutional amendment is a daunting task, requiring the support of two-thirds of the U.S. House and Senate, followed by ratification by three-fourths of the 50 state legislatures.

Cobb believes that it will take about 10 years to build a grassroots movement to successfully lobby for the enactment of the amendment, but that it can be accomplished eventually.

“It’s a lot of work, but so was the Civil Rights Movement, so was women’s suffrage,” Cobb told IPS.

“A small group of ruling elites has hijacked every one of the institutions in this country – the media and both political parties. There’s a corporatized culture and we have to change the power structure. The only way we see is to build a mass, multiracial movement,” he said.

“Move to Amend is a coalition coming together specifically to work together for (abolishing) corporate personhood. We’ve got 258,000 people who are participating with us specifically on this project. There’s lots of work going on now, and it’s coalescing.”

The effort to amend the U.S. constitution has in part been a reaction to the controversial ruling of the Supreme Court in Citizens United v. Federal Election Commission in 2010, which found that the first amendment to the U.S. constitution, on freedom of speech, prohibits the government from restricting independent political expenditures by corporations and unions.

In the ruling, corporations were essentially viewed as having the same rights as people, thus coining the term corporate personhood.

Activists held rallies across the U.S. earlier this month to protest the third anniversary of the Citizens United ruling.

Data from the 2012 national elections have begun to reveal an unprecedented amount of spending in the elections, about six billion dollars, much of which is untraceable due to a new phenomenon called SuperPACs, political action committees that have literally no limit to how much they can spend, as well as shadow corporations, which are created for the sole purpose of funneling money into elections.

One of the main organizing strategies by MTA and other groups to support an eventual constitutional amendment is to get local councils and commissions at the city and county levels to adopt resolutions in support of such an amendment.

According to the MTA website, there are at least 183 municipal government resolutions, 19 local ordinances, and three state-level resolutions in Hawaii, Montana, and Vermont that have passed to ban corporate personhood.

In addition, there are 79 local resolutions and 10 state resolutions that have also passed, but that MTA considers partial resolutions because they do not completely address the issue of corporate constitutional rights.

Most recently, on Jan. 22, the city council in Conway, Arkansas, passed a resolution with unanimous support.

MTA is itself a coalition of hundreds of organizations, and MTA has dozens of affiliates in cities throughout the U.S.

Other organizations that are working on this issue nationally include United for the People, which is also a coalition and which also has affiliates, in addition to Free Speech for the People, People for the American Way, and Public Citizen.

There has been some disagreement, though, among members of congress and various advocacy groups as to what the exact language of the constitutional amendment should be.

At least six different members of congress introduced legislation in 2011 to amend the constitution to in one way or another address the issue of unlimited corporate spending in U.S. elections.

Meanwhile, different organizations are supporting different versions of the bill. For example, Free Speech for the People is supporting the Edwards proposal and the McGovern proposal. People for the American Way is supporting the Udall proposal. And Public Citizen is supporting the Deutch proposal, which is the counterpart in the House to the Sanders proposal in the Senate.

Move to Amend presents on its website what it believes to be the strongest version of the proposed amendment, adding, “It is our belief that we need to operate on the assumption that once an Amendment comes out of Congress we won’t get another shot. So we MUST get it right!”

“I work on many issues. When you get to the bottom of just about every issue, you come up against the wall of the unholy alliance of money, corporate interest, and politicians,” Stacey Hopkins, lead organizer for United for the People Georgia and council organizer for MoveOn Atlanta, told IPS.

“I was active in doing voter registration, and we saw where dark money groups were backing voter suppression efforts around the country,” Hopkins said.

“We’ve also seen groups backing efforts to repeal Section Five of the Voting Rights Act, and as an African American, this is something that I take very personally,” Hopkins said.
