November ballot

Proposition 50 would shift the state’s congressional district lines to favor Democrats. It is Gov, Gavin Newsom’s response to a similar effort in Texas designed to put more Republicans in Congress. The new district lines would override those created by the state’s nonpartisan, independent redistricting commission.

Supporters include Democratic politicians and party organizations and labor unions. Newsom has said that this is a needed step to counter President Trump and to protect Californians. Republicans oppose the measure, arguing that partisan maps would take the state backward.

Overall fundraising

The Times is tracking contributions to one committee supporting Proposition 50 and two committees opposing the measure. Many committees have contributed to these main committees.

How money has flowed in over time

Since the proposal was announced in August, donations supporting the measure have poured in.

Biggest supporters

The Times is tracking contributions to the main fundraising committee supporting Proposition 50, which is controlled by Newsom. George Soros’ Fund for Policy Reform is the top donor with $10 million. House Majority PAC, the second-largest donor, aims to elect Democrats to the U.S. House of Representatives. Labor unions are also major supporters.

The measure has received support from several business executive and philanthropist donors, including Michael Moritz, Gwendolyn Sontheim and Reed Hastings.

Almost 150,000 individuals gave $100 or more. More than $11 million, about 14% of the total raised, came from small-dollar contributors, or those who gave less than $100.

Biggest opposition

The Times is also tracking contributions to two main opposition committees. Most of the money to these groups has come from extremely large contributions from a handful of donors.

Charles Munger, Jr., son of the former Berkshire Hathaway vice chairman, contributed more than $32 million to the Hold Politicians Accountable PAC.

Small-dollar contributions have made up $7,500 of the total raised.

The Congressional Leadership Fund has given $5 million to the Stop Sacramento’s Power Grab committee.

Millions of dollars began flowing into campaigns supporting and opposing an effort to redraw California’s congressional districts on the November ballot, notably $10 million from independent redistricting champion Charles Munger Jr.

The checks, reported Friday in state campaign finance disclosures, were made on Thursday, the day the state Legislature and Gov. Gavin Newsom called a special election to replace the congressional districts drawn by an independent commission in 2021 with new districts that would boost the number of Democrats elected to Congress in next year’s midterm election.

The move is an effort by California Democrats to counter Texas Republicans’ and President Trump’s efforts to boost the number of GOP members.

Munger, a GOP donor and the son of a billionaire who was Warren Buffett’s right-hand man, bankrolled the 2010 ballot measure that created independent congressional redistricting in California. He donated $10 million to the “No on Prop. 50 – Protect Voters First” campaign,” which opposes the proposed redistricting.

“Charles Munger Jr. is making good on his promise to defend the reforms he passed,” said Amy Thoma, a spokesperson for the Voters First Coalition, which opposes the ballot measure and includes Munger.

A spokesperson for the campaign supporting the redrawing of congressional boundaries accused Munger of trying to boost the GOP under the guise of supporting independent redistricting.

“It’s no surprise that a billionaire who has given extensively to help Republicans take the house and [former Republican House Speaker] Kevin McCarthy would be joining forces to help Donald Trump steal five House seats and rig the 2026 midterm before a single American has voted,” said Hannah Milgrom, spokesperson for “Yes on 50: the Election Rigging Response Act.” “Prop 50 is America’s best chance to fight back – vote yes on November. 4.”

The campaign backing the ballot measure received $1 million on Thursday from a powerful labor group, SEIU’s state council; $300,000 from businessman Andrew Hauptman; and a flurry of other donations, according to the California secretary of state’s office. That is on top of the $5.8 million the campaign reported having in the bank as of July 30, including millions of dollars in contributions from House Majority PAC, which is focused on electing Democrats to Congress, and Newsom’s 2022 gubernatorial reelection campaign.

Redistricting typically happens once a decade after the U.S. census. Trump asked Texas lawmakers to redraw their congressional districts earlier this year, arguing that the GOP was entitled to five more members from the state. In response, California Democrats have pitched new district boundaries that could result in five more Democrats being elected to Congress.
