From the article:
The political action committee set up by billionaires angry about the proposed wealth tax on the November ballot has raised an astonishing $91 million in the last seven weeks alone from wealthy individuals.
Building a Better California was established in February, as billionaires’ concern over the measure ramped up. Google co-founder Sergey Brin, who is the driving force behind the committee, gave another $20 million in July, upping his total to $102 million. Building a Better California has raised $229 million total since launching.
The measure did not officially qualify for the November ballot until mid-June. The group has pumped money into opposing the tax, now Prop 40, and into backing two measures — Props 41 and 42 — meant to nullify or blunt the tax if it does pass. The number of individuals giving more than $1 million to the PAC is staggering, even by the standards of California’s unwieldy, expensive election landscape.
Proposition 50, the Gov. Gavin Newsom-led 2025 ballot measure that temporarily redrew California’s House district boundaries, received 25 donations of at least $1 million, and his 2021 anti-recall committee had 22 such donations. But only four of the Prop 50 or anti-recall committee’s million-dollar donors were individuals, said Rob Pyers, director of research at the California Target Book, a nonpartisan compendium of California political information. The other donors to the Newsom-led efforts were “union groups, tribal organizations or other committees,” Pyers said.
Meanwhile, Building a Better California has 20 donors who have contributed $1 million or more, all of them individuals.
