From the billionaire tax to voter ID, here are the 14 measures Californians will decide in November

California voters will weigh in on 14 statewide ballot measures in the Nov. 3 election — covering taxes, housing, healthcare funding, climate policy, election rules and public campaign finance.

The proposals include competing tax plans, major borrowing measures for housing and medical research, changes to environmental review timelines, and new rules for voting and campaign financing.

Here’s what’s on your November ballot:

Billionaire tax

Gov. Gavin Newsom, Sergey Brin, Chris Larsen, California Medical Association, California Teachers Association and the California Primary Care Association.
