A group seeking to ban corporate campaign contributions to candidates for elected office in D.C. is set to announce today that volunteers gathered over 30,000 signatures to put the proposed ban on November’s ballot.

The proposal, known as Initiative 70, would prohibit corporations from giving to political campaigns, legal defense funds, transition funds and constituent services funds. (Twenty-one states and the federal government have similar bans in place.) Currently, corporations are allowed to give money for local campaigns, and good government activists has said that businesses and moneyed interests have bundled contributions to candidates, giving them an outsized level of influence in local politics.

The signature-gathering process was launched in January by former D.C. Council candidate Bryan Weaver. Under D.C. law, it would have to gather some 23,000 signatures from D.C. voters, including signatures from five percent of registered voters in five of the city’s eight wards, to get on the ballot. According to a press release, more than 300 volunteers for the D.C. Public Trust gathered over 30,000 signatures, which will be delivered to the D.C. Board of Elections and Ethics today. In six of eight wards they exceeded the five percent mark, said the release.

“D.C. residents want to see Initiative 70 on the ballot,” said Weaver. “Our volunteers have gotten a tremendous response from residents across the city. It’s clear that D.C. residents are fed up with the pay-to-play culture in the Wilson Building and are tired of waiting for our elected officials to do the right thing.”

Critics of the measure say that it would simply push corporations to donate money to political action committees instead of directly to candidates, who have to disclose the donations on campaign finance reports. A recent campaign finance overhaul proposal presented by Mayor Vince Gray would not do away with corporate giving, but rather require stricter disclosure requirements.
