California’s $100 Million Redistricting Battle: Trump vs. Newsom – Will California Voters Approve a Mid-Decade Redraw of Congressional Boundaries?

In the final 74 days leading up to the November election, California Democrats are engaged in a battle to persuade voters to approve a mid-decade redrawing of congressional boundaries. The objective is to counter President Donald Trump’s attempts to maintain Republican power in Washington, potentially securing five additional US House seats for the Democratic party.

Opposition to this redistricting plan includes an unlikely alliance of Republican leaders, good-government advocates, and former GOP Governor Arnold Schwarzenegger. They will argue that Californians should remember why they removed lawmakers’ redistricting powers 15 years ago. Unlike in Texas, California’s constitution assigns the task of drawing congressional lines to an independent redistricting commission.

The short timeline for convincing voters is further complicated by California’s reliance on mail-in ballots, with voting materials expected to reach households within a month. Both sides anticipate an increase in political advertisements across television, digital devices, and mailboxes in the coming weeks.

“It’s really a September campaign,” said Amy Thoma Tan, spokeswoman for Protect Voters First, an opposition group funded by Charles Munger Jr., son of the late-Berkshire Hathaway vice chair. Munger has vowed to use his wealth to defend California’s independent redistricting commission. Former House Speaker Kevin McCarthy will support another opposition group, Stop Sacramento’s Power Grab, with funding from Republicans.

Munger’s group is expected to target independent voters, while McCarthy will focus on encouraging Republican turnout for the unexpected off-year election. Spending in California during this period is anticipated to exceed nine figures and become the year’s most expensive political contest.

Newsom and Democrats argue that the constitutional amendment, known as Proposition 50, offers a unique opportunity for Californians to counter Trump’s power grab in Texas. Republicans are sensitive to Trump’s unpopularity in California, with only one-third of voters approving of his job performance, according to a May poll from the Public Policy Institute of California.

While Newsom has made clear his intention to deliver a victory for the Democratic Party and boost his presidential ambitions, his approval rating suggests that many voters may be hesitant to support him. The outcome of this battle could significantly impact control of the House of Representatives during Trump’s second term.
