California voters split on billionaire tax and voter ID proposals, poll shows

According to a recent California Post poll, over 50% of voters reject the billionaire tax measure known as Proposition 40, reflecting skepticism toward Sacramento officials and worries about a recurring tax burden. Pollster John McLaughlin noted that messaging about loopholes and broader tax implications resonates with the electorate. In contrast, Proposition 39, which would mandate government-issued identification for in-person voting and on mail ballot envelopes, is nearly tied at 45.6% support and 47.8% opposition, with Republicans largely in favor and Democrats opposed.

The poll also highlights that billionaire Sergey Brin has spent more than $100 million fighting the tax and donated an additional $20 million to Build a Better California, an organization campaigning against the measure. Voter-ID opposition is further fueled by concerns over the ballot title’s wording, which warns that the measure could “prohibit citizens from voting.” The state’s November 3 election will decide both propositions.
