As super PACs and “dark money” nonprofits are often so reliant on contributions from a handful of wealthy individuals, a powerful group can lose influence quickly if a single donor decides to jump ship.
For example, American Unity PAC, which works to elect pro-LGBT Republicans, saw its independent expenditures fall from $4.8 million in 2014 to $930,667 in 2018 as the group’s revenue dropped to an all-time low since its founding in 2012. New York hedge fund manager Paul Singer, who advocates for legalizing same-sex marriage, started the super PAC with an influx of cash and regularly contributed millions of dollars. But in 2018, his contributions to American Unity PAC dropped to just over $1 million as he instead directed $2 million to the conservative Senate Leadership Fund (SLF).
