Elizabeth Simons, the billionaire daughter of late hedge-fund titan James Simons, is funneling hundreds of thousands of dollars to the Democrats' official House campaign arm, even as she simultaneously finances a super PAC backing a democratic socialist in New York.
Simons donated $354,000 to the Democratic Congressional Campaign Committee this election cycle and cut additional checks to individual House candidates, the New York Post reported, citing an analysis of Federal Election Commission data. She also gave $250,000 last August to New Yorkers for Lower Costs, the super PAC supporting Zohran Mamdani, a self-described democratic socialist running against former Gov. Andrew Cuomo. That quarter-million-dollar check was the largest single contribution the group had received.
The dual-track spending raises a straightforward question: What exactly is Simons buying? She is funding the party's establishment campaign committee, which exists to elect mainstream Democrats and protect incumbents, while also bankrolling a socialist candidate and progressive organizations that openly seek to dismantle that same establishment from within.
Simons is not operating alone. She is one of four California-based megadonors who have combined to contribute nearly $4 million to House Democrats and Democratic committees this election cycle, according to the FEC data analysis. The other three are Patty Quillin, wife of Netflix CEO Reed Hastings; Kaitlyn Krieger, wife of Instagram co-founder Mike Krieger; and Quinn Delaney, a foundation executive married to California real estate developer Wayne Jordan.
Quillin gave more than $300,000 to the DCCC on her own. But she also contributed $650,000 to the Working Families Party, one of several groups committed to taking down the Democratic Party establishment and replacing centrist incumbents with further-left candidates. The Working Families Party crowed last week about adding Michigan House primary winner Will Lawrence and U.S. Senate primary winner Abul El-Sayed to what it called "the growing list of WFP-backed candidates winning grueling primaries in purple seats."
Quillin runs the Meadow Fund, a donor-advised fund housed at the Silicon Valley Community Foundation. Delaney founded and chairs the Akonadi Foundation, which describes its mission as supporting "the development of powerful social change movements to eliminate structural racism and create a racially just society." Krieger and her husband run a nonprofit focused on criminal justice issues.
This is not a new pattern. In the 2022 election cycle, Simons and three other California heavy hitters donated $22 million to ballot measures and candidates, according to Politico. The scale has only grown.
Elizabeth Simons's father, James Simons, founded Renaissance Technologies, one of the most successful quantitative hedge funds in history. When he died in 2024, his estimated net worth stood at $31.4 billion. His daughter co-founded the Heising-Simons Foundation with her husband, Mark Heising, and now chairs its board of directors.
The foundation's grant-making offers a window into the ideology behind the political checks. The Heising-Simons Foundation has contributed $1.7 million to the Racial Justice in Early Mathematics Project at the Erikson Institute in Chicago, a program that filters grade-school arithmetic through a racial-justice lens. Simons and her foundation did not respond to a request for comment on her contributions and strategy.
The National Republican Congressional Committee wasted no time drawing the connection between the donors' progressive philanthropy and the candidates their money supports. NRCC spokeswoman Emily Tuttle put it bluntly:
"Democrats aren't just embracing a socialist, anti-police agenda, they're being bankrolled to do it. Every Democrat backing this radical, pro-crime platform will answer to voters this fall."
Republicans currently hold a 218, 212 House majority, a margin thin enough that a handful of flipped seats would hand the Speaker's gavel to Hakeem Jeffries. The DCCC, headed by Rep. Suzan DelBene of Washington state, a member of the centrist New Democrat Coalition, is the party's chief instrument for winning those seats. Jeffries has positioned himself as the leader who can hold the party's center, but the money flowing into his campaign apparatus comes from donors whose other investments point sharply leftward.
One longtime Democratic fundraiser acknowledged the tension but framed it as pragmatism:
"I can see why a lot of the very woke left is lining up with Hakeem [Speaker Jeffries] because the goal is winning the House."
That reasoning deserves scrutiny. If the goal is simply winning the House, why simultaneously fund organizations like the Working Families Party, whose explicit purpose is to primary the very centrist Democrats the DCCC recruits? Why write a $250,000 check to a super PAC backing a democratic socialist against a former governor? The money tells a story that the talking points do not.
The pattern is consistent across all four megadonors. They write large checks to the official party committee, the kind of contributions that buy access and goodwill with leadership. At the same time, they fund activist organizations, progressive primary challengers, and ideological nonprofits that push the party further from the center. The DCCC deposits the money. The Working Families Party spends its share trying to defeat the DCCC's preferred candidates.
Simons's $354,000 to the DCCC and her $250,000 to a socialist's super PAC are not contradictory if you understand the strategy: fund the party broadly enough to win the majority, then use separate vehicles to ensure the majority is filled with members who share your ideological commitments. It is not a donation. It is an investment portfolio, diversified for maximum leftward return.
Voters in competitive House districts deserve to know that the same California billionaires writing checks to their Democratic candidates are also bankrolling groups that want to defund police, inject racial ideology into children's math classes, and replace moderate Democrats with self-described socialists. The DCCC can cash those checks, but it cannot pretend the money comes without expectations.
When the same hand writes a check to the establishment and to the people trying to overthrow it, the hand is not confused, it just expects to own whatever comes next.
