The rally urged state legislators to pass a resolution asking for an amendment to overturn Citizens United.
After the 5-4 Citizens United ruling allowing corporations to make unlimited financial donations to independent political groups, some corporations obscured their identities by creating new political action committees or other entities to funnel their donations.
Shortly before Tuesday's rally began, the U.S. Supreme Court accepted an appeal in McCutcheon v. Federal Election Commission -- a campaign finance case seeking to remove limits on contributions individuals can donate during two-year federal election cycles.
The National Republican Committee and Shaun McCutcheon, an Alabama resident, are challenging the current "aggregate limits" on individual contributions -- 46,200 in contributions to individual candidates and $70,800 to political committees during every two-year election cycle.
The U.S. Court of Appeals for the District of Columbia previously ruled to uphold the current limits.
Gary Zuckett, executive director of CAG, said, "Considering the previous unfortunate decisions this Supreme Court has given us on election law, I am concerned they may further open the floodgates to unlimited money in our electoral process.
"It is ironic that on a day when more than 100 citizens rallied at our state Capitol against the flood of unregulated money, the U.S. Supreme Court would agree to take this case."
Jonah Minkoff-Zern, a senior organizer for Public Citizen, said during an interview after the rally, "The Citizens United ruling is already having a disastrous impact on our democracy.
"To rule that individuals can give unlimited amounts directly to candidates would further deepen the corrupting influence of money on our political system.
"In the 2012 elections, 47 wealthy individuals gave a total of $130 million to super PACs. It destroys any semblance of democracy when their voice matters so much more than mine.
"It is hopeful that people are rising up against the Supreme Court ruling in Citizens United. For us to have a democracy, we cannot allow billions of dollars to be spent on our elections," Minkoff-Zern said.
