Bernie Sanders rallied supporters at The Wiltern in Los Angeles, throwing his weight behind a proposed one-time 5% wealth tax on California billionaires and declaring that for the ultra-rich, “enough is never enough.” The initiative, formally tracked as a constitutional amendment under Initiative 25-0024A1, would affect roughly 200 people and direct the vast majority of revenue toward health care programs. Sanders’ campaign stop immediately sharpened a growing rift with Gov. Gavin Newsom, who has come out forcefully against the measure, setting up one of the most consequential intra-Democratic fights of the 2026 election cycle.
What the Ballot Measure Would Do
The proposed California One-Time Wealth Tax for State-Funded Health Care Programs Initiative would impose a one-time 5% tax on the net worth of California residents who qualify as billionaires as of January 1, 2026. The tax would be due in 2027, though taxpayers could spread payments over five years, and it would not apply to future wealth or to those who fall below the billion-dollar threshold. According to a revenue analysis published by economists at UC Berkeley, the levy would generate an estimated $100 billion in additional revenue for the state over the 2027-to-2031 period under the baseline case, with the authors arguing that even under pessimistic assumptions about relocations, the state would still see tens of billions in net new funds.
The revenue split written into the measure directs 90% of proceeds to state-funded health care programs, including Medi-Cal, and 10% to public education. SEIU-United Healthcare Workers West, the labor union driving the signature campaign, says the tax would apply to approximately 200 people in a state that is home to several of the wealthiest people in the world, including tech founders and investors whose fortunes surged over the last decade. The California Attorney General has already issued a title and summary for the initiative, and signature collection is underway. Supporters must gather nearly 900,000 valid signatures from California voters to place it on the November 2026 ballot, a threshold that reflects a percentage of turnout in the last gubernatorial election and that has historically proved challenging for grassroots campaigns without substantial financial backing.
Sanders vs. Newsom: A Democratic Divide
Sanders’ appearance in Los Angeles put him squarely at odds with Newsom, a high-profile Democrat who has cultivated a national following and is often mentioned in conversations about future presidential contenders. Where Sanders argued that billionaires’ unchecked power threatens democratic governance, Newsom has opposed the measure as excessive and potentially damaging to the state’s economy, warning that it could accelerate an exodus of wealthy residents and undermine California’s already volatile revenue base. The split is unusual: both figures draw from the same Democratic base, yet they have staked out irreconcilable positions on whether taxing concentrated wealth is a practical tool or a recipe for capital flight, with Sanders dismissing relocation threats as overblown and Newsom emphasizing fiscal risk.
That disagreement matters beyond California. Newsom’s opposition aligns with a strain of Democratic thinking that treats business-friendly tax policy as essential to keeping tech companies and high-net-worth residents in the state, even as the party embraces higher income and corporate taxes at the federal level. Sanders, drawing on the same populist energy that fueled his 2016 and 2020 presidential runs, frames the tax as a moral question about whether a handful of billionaires should hold more wealth than millions of working families combined. At the Wiltern rally, he told the crowd that billionaires already wield outsized influence over elections and policy and that a one-time levy is a modest corrective, not a radical step. As reported in a separate account of his California swing, Sanders has also cast the fight as a test of whether Democrats are willing to confront their own donors, a message that could shape how primary voters think about wealth taxation heading into the 2028 presidential cycle.
Republican Countermove From Congress
The fight is not limited to Democrats. Congressman Kevin Kiley, a Republican representing parts of California, introduced the Keep Jobs in California Act in Washington on February 18, the same day Sanders headlined the Los Angeles kickoff. Kiley’s bill would offer federal tax credits to residents who leave California because of new wealth taxes and seeks to limit the state’s ability to tax assets that are difficult to value or located outside its borders, echoing arguments advanced by billionaire investors who say such levies are unworkable. By tying his proposal to concerns about entrepreneurship and innovation, Kiley is trying to turn the billionaire tax into a broader referendum on California’s business climate at a time when the state is already grappling with budget shortfalls and high-profile corporate relocations.
The timing was deliberate. By filing the legislation on the eve of Sanders’ rally, Kiley signaled that opponents plan to fight the measure on multiple fronts, not just through the California ballot process but through congressional action as well. Whether a Republican-led federal bill could preempt a state constitutional amendment is a contested legal question, and tax law experts note that states traditionally have wide latitude to design their own revenue systems. Still, the move gives business groups and wealthy donors a parallel track to challenge the tax even if it qualifies for the ballot, and it helps national Republicans frame the California proposal as a cautionary tale for other states. It also creates an odd-bedfellows dynamic: Newsom and Kiley, who agree on little else, both want to stop the measure, though for very different stated reasons and with sharply contrasting constituencies.
The Signature Race and What Comes Next
The most immediate hurdle for the initiative is the signature threshold. Backers need to collect nearly 900,000 valid signatures to qualify the measure for the November 2026 ballot, a task that must be completed within a tight calendar window. SEIU-United Healthcare Workers West is leading that effort, and the union’s organizational reach across hospitals and care facilities gives it a built-in network of petition circulators who can approach patients, families, and staff with pitches that link the tax to expanded coverage and better staffing. According to reporting on the early stages of the campaign, organizers are targeting both major metropolitan areas and smaller inland communities, betting that frustration with health care costs and corporate profits can bridge California’s regional divides.
Sanders’ involvement is designed to supercharge that organizing push. His Los Angeles rally drew thousands of supporters and generated national media coverage, with Newsom’s criticism of the tax as “excessive” becoming a focal point of the story. Supporters hope that attention will translate into volunteers and small-dollar donations, while opponents are preparing a well-funded media campaign that highlights fears of capital flight and legal uncertainty. National coverage from outlets like the Associated Press has underscored how unusual it is for a single-state tax proposal to draw this level of outside interest, suggesting that California’s billionaires’ tax could become a template, or a warning, for other blue states weighing similar ideas.
Even if the measure qualifies for the ballot, the path to passage will be steep. Californians have a mixed record on tax hikes, approving some measures aimed at high earners while rejecting others seen as too broad or poorly designed. Polling cited in early coverage indicates that voters like the idea of asking billionaires to pay more but grow more skeptical when confronted with arguments about administrative complexity and the possibility of wealthy residents moving away. Business groups are expected to emphasize those concerns, while unions and progressive organizations will highlight stories of underfunded clinics and schools that they say could benefit directly from the new revenue.
The legal landscape is also uncertain. Courts have not yet weighed in on a one-time net worth tax of this kind, and opponents are likely to challenge both its valuation methods and its treatment of assets held through trusts and out-of-state entities. Supporters counter that the measure is carefully drafted to withstand scrutiny, citing the non-recurring nature of the levy and its focus on residents who meet a clear wealth threshold as of a specific date. However those arguments play out, the fight over California’s billionaire tax is already reshaping the national debate over inequality, pitting a populist call to tap extreme fortunes for public goods against warnings that such moves could erode the very tax base that funds those services.
