In blocking his party’s push for new taxes on stock trades, capital gains, and carried interest, New York governor Andrew Cuomo is protecting the financial industry that has delivered millions to his campaign and political operation, according to state records reviewed by me. That includes the single-largest donor to the state Democratic Party during Cuomo’s 2018 reelection bid, who just delivered large donations to Cuomo as the governor has stymied the tax proposals.

Last month, billionaire James Simons and his wife gave Cuomo $90,000. Simons is the founder of the hedge fund Renaissance Technologies, which could be subject to the new levies being pushed by New York Democratic legislators. In total, Cuomo has received over $280,000 from Simons and his family. The Cuomo-controlled New York Democratic Party has received an additional $3.4 million from Simons.

Cuomo’s political machine has received big donations from other hedge fund moguls including Dan Loeb ($197,000) and Stanley Druckenmiller ($60,800), who could also be impacted by the Democratic tax initiatives aimed at the financial industry.
