'A stark illustration of our broken campaign finance system': Here's how rich mega-doners hacked US politics

Just 12 megadonors contributed roughly $1 in every 13 dollars spent on recent campaigns for federal office, as well as the political groups that make up the U.S. campaign finance system, according to a new report on the influence of money in politics.

The staggering sum of these contributions — which represent more than $3.4 billion over the last decade — was revealed on Tuesday by Issue One, a nonpartisan group dedicated to reducing "the corrosive influence of big money in politics."

The findings offer a stark quantification of the role that a shrinking number of super-rich megadonors, both individuals and couples, have played in American politics following the Supreme Court's 2009 Citizen's United ruling. According to the report, all 12 of the country's top political donors are white, and the group represents more than a quarter of all donations from the top 100 zip codes by political contributions — which are more likely to skew white and affluent.

"Our government can't be responsive to all Americans if our elected officials are beholden to the elite donor class," Nick Penniman, Issue One's founder and chief executive, said in a statement. He added that Congress should act immediately to "pass sweeping reforms to create a democracy that works for everyone."

The top 12 donors were split equally down the middle among Democrats and Republicans. They were led by former New York City Mayor Michael Bloomberg and hedge fund manager Tom Steyer. Both men self-funded their own Democratic presidential campaigns in 2020, with Bloomberg reportedly putting more than $1 billion and Steyer more than $200 million toward their doomed White House bids.

Top Republican donors included the late casino mogul Sheldon Adelson and Dr. Miriam Adelson, his widow who received the Medal of Freedom under former President Donald Trump; shipping magnates Richard and Elizabeth Uihlein; hedge fund manager Ken Griffin; Timothy Mellon, the scion of one of America's wealthiest industrial-age families; TD Ameritrade founder Joe Ricketts and his wife Marlene; as well as hedge fund manager Paul Singer.

On the Democratic side, other top contributors included hedge fund managers Donald Sussman and Jim Simons, media mogul Fred Eychaner and Facebook co-founder Dustin Moskovitz.

The list does not include state and local level donations.

These trends lend to a climate where Americans are "losing faith in our democratic institutions," Issue One Executive Director Meredith McGehee said in a statement. "Congress must urgently act to restrain the growing influence of money in our politics and build a system that truly represents all Americans — not just the wealthy few."
