Documents reveal massive 'dark-money' group boosted Democrats in 2018

The “green wave” of campaign cash that boosted Democrats and liberal causes in 2018 included an unprecedented gusher of secret money, new documents obtained by POLITICO show.

The Sixteen Thirty Fund, a little-known nonprofit headquartered in Washington, spent $141 million on more than 100 left-leaning causes during the midterm election year, according to a new tax filing from the group. The money contributed to efforts ranging from fighting Supreme Court Justice Brett Kavanaugh and other Trump judicial nominees to boosting ballot measures raising the minimum wage and changing laws on voting and redistricting in numerous states.

The spending was fueled by massive anonymous donations, including one gift totaling $51.7 million. That single donation was more than the group had ever raised before in an entire year before President Donald Trump was elected. Most of the group's funders are likely to remain a mystery because federal law does not require "social welfare"-focused nonprofits to reveal their donors.

The group's 2018 fundraising surpassed any amount ever raised by a left-leaning political nonprofit, according to experts, who pointed to the Koch network and the Crossroads network as rare right-leaning groups that posted bigger yearly fundraising totals at the height of their powers.

The Sixteen Thirty Fund’s rise last year is a sign that Democrats and allies have embraced the methods of groups they decried as “dark money” earlier this decade, when they were under attack from the money machines built by conservatives including the Kochs.
