BOSTON (AP) — Massachusetts is pushing ahead with efforts to amend the U.S. Constitution to restore limits on political spending by corporations.

A state commission charged with weighing potential constitutional amendments aimed at countering the Supreme Court’s 2010 Citizens United decision released an interim report Wednesday updating its progress.

Members of the Massachusetts Citizens Commission said the goal of the amendment would be to give Congress and states the power “to regulate contributions and expenditures in our federal, state, and local elections to secure the free speech and representation rights of all Americans, combat corruption and protect the integrity of elections.”

A ballot question approved by Massachusetts voters in 2018 created the commission.

The report pointed to a sharp rise in spending in elections. Most of that spending is concentrated in the hands of a small slice of the electorate, the commission said. Citizens United helped open the door to allowing businesses, unions and nonprofits to spend unlimited amounts to influence elections.

Costas Panagopoulos, co-chair of the commission, said the group hopes to have proposed language for a constitutional amendment in a final report by the end of June.

The push in Massachusetts is one of several efforts by states to respond to the Citizens United decision.

Massachusetts Attorney General Maura Healey said no one person’s voice should be louder or more important than anyone else’s. She said Citizens United changed that by concentrating political spending in the hands of an increasingly smaller number of donors.

“Fundamentally it’s about fairness. It’s about democracy,” said Healey, a Democrat. “In Massachusetts we believe democracy is about people, not money.”

Critics of the effort in Massachusetts say they agree with the Citizens United decision that free speech protections can extend to some forms of political contributions.

They also argue that the birth of social media has helped ensure anyone can broadcast their views to a large audience even without money.

The Citizens United ruling helped make it easier for corporations and unions to spend unlimited amounts of money trying to persuade voters to cast their ballots for or against a candidate.

While the ruling did not lift the ban on companies and unions giving money directly to candidates for federal office, it let them spend money trying to influence voters as long as the money was not being spent in coordination with a campaign.

There have been just 27 amendments added to the Constitution — including the first 10, the Bill of Rights, ratified in 1791.

Adding an amendment to the Constitution requires approval by two-thirds of the U.S. House and Senate and ratification by three-fourths of the states, 38 in all.
