Sanders and Khanna Rally in California as Billionaire Tax Fight Intensifies

Key points

• Proposition 40 proposes a one-time 5% tax on the wealth of approximately 200 California billionaires, with revenue directed toward federal Medi-Cal cuts.
• Gov. Gavin Newsom opposes the measure, arguing it will cause billionaires to relocate and reduce state tax revenue, while proposing a national tax on loans against assets instead.
• The 'No on Prop 40' coalition, funded largely by billionaires like Sergey Brin and Eric Schmidt, has raised over $252 million, vastly outspending the 'Yes on 40' campaign, which has raised about $32.4 million.
• Legal experts debate whether the measure's legislative amendment clause allows lawmakers to expand the tax to non-billionaires, with courts likely to rule on any such attempts based on the original voter intent.
• Nvidia CEO Jensen Huang has stated he is willing to pay the tax, contrasting with other tech leaders like Larry Page and Sergey Brin who have reportedly relocated to avoid it.

Background

This debate follows earlier polls showing a slight majority support for Prop 40, though two other Brin-funded measures could nullify it if passed. Previous coverage noted internal conflicts within the SEIU union regarding the campaign and a shift in San Francisco’s Democratic Party toward opposing the state-level tax in favor of a national solution. The current campaign is part of a broader 2026 election cycle where wealth taxation is a central issue for potential 2028 presidential candidates.

How outlets are covering it

ABC News and Politico emphasize the political clash between Sanders/Khanna and Newsom, highlighting the massive spending disparity and the argument that billionaire influence is undermining democracy. CalMatters provides a more technical analysis, focusing on the legal ambiguity of the measure’s amendment clause and the difficulty of valuing illiquid assets. While ABC and Politico frame the opposition as a 'billionaire takeover,' CalMatters notes that the 'slippery slope' argument regarding expansion to non-billionaires is legally complex and not guaranteed, though possible. All sources agree that the measure is a pivotal test for wealth taxation in the US.

Why it matters

The outcome of Proposition 40 will set a precedent for state-level wealth taxes and influence the 2028 presidential race. If passed, it could generate significant revenue for healthcare but may also trigger a mass exodus of the ultra-wealthy, reducing long-term tax revenue. The intense spending war highlights the growing influence of billionaire donors in state politics and the potential for ballot initiatives to be nullified by countermeasures.

What to watch

Early voting is underway in California, with the general election approaching. The 'No on Prop 40' campaign is running digital ads warning of revenue loss and tax expansion, while supporters are focusing on grassroots outreach. Legal challenges may arise if the measure passes and lawmakers attempt to amend it. The results will likely influence the strategies of 2028 presidential candidates, including Newsom and Khanna, regarding their stances on wealth taxation.
