Dark money groups have pumped $1 billion into GOP campaigns to recapture Senate

Shadowy organizations that are legally allowed to hide their donors have pumped nearly $1 billion into the Republican Party's effort to retake the U.S. Senate, according to an NPR analysis released Saturday.

In total, NPR found that "more than $1.6 billion has been spent or booked on TV ads in a dozen Senate races, with $3 out of every $4 being spent in six states — Georgia, Pennsylvania, Arizona, Wisconsin, Nevada and Ohio."

"Most of that money is coming from dark money outside groups with little-to-no donor transparency — and Republicans are getting a huge boost from them," the outlet reported.

Nearly 90% of the money spent on pro-Republican television ads this midterm cycle has been from dark money groups, according to NPR's analysis of ad data. By comparison, 55% of spending on ads boosting Democrats has come from dark money organizations, which have exploded in number and influence since the Supreme Court's 2010 Citizens United decision.

Predictably, key battleground states such as Georgia, Pennsylvania and Arizona have drawn massive ad spending from outside groups in recent months, as Senate races in those states tighten with just over two weeks until the November midterms.

Outside organizations have poured more money into Pennsylvania — where Democratic Lt. Gov. John Fetterman is locked in a competitive Senate contest with Republican nominee Dr. Mehmet Oz — than any other state this cycle.

"Outside groups have spent nearly $64.9 million to back Fetterman or sway voters away from the celebrity doctor, while conservative outside spenders have poured $66 million into the race," OpenSecrets noted Friday. "One of the top outside spenders is the Senate Leadership Fund," a super PAC aligned with Senate Minority Leader Mitch McConnell, which has "made Fetterman their top target, spending almost $37.2 million to oppose the Democrat."

NPR's analysis came a month after Senate Republicans unanimously voted down legislation that would have required dark money organizations to disclose their large donors and funding sources, a step that would shine light on the forces attempting to sway critical races.

OpenSecrets discovered last month that a newly created dark money group that has spent big on ads mocking and attacking progressive candidates in battleground states is "connected to officials in former President Donald Trump's administration who now work with the America First Legal Foundation."

"The group, Citizens for Sanity, has paid for billboards emblazoned with messages like 'Protect Pregnant Men from Climate Discrimination' and 'Real progressives support violent criminals in their hour of need' in states across the country — including Massachusetts, Colorado, Arizona, Nevada, Pennsylvania, California, Michigan, Texas, Illinois and Georgia," the watchdog noted. "The ads have been described as racist and transphobic."

"Federal Communications Commission records reviewed by OpenSecrets reveal that the group's board includes three former Trump administration officials involved in the America First Legal Foundation, a group founded by former Trump White House official Stephen Miller," OpenSecrets added.
