Prognosis

Not enough signal yet

Not enough signal yet to read this bill's trajectory — we surface a likelihood only once there's real movement (stage, sponsorship, committee, or votes) to point to.

Summary

The California Constitution establishes the Citizens Redistricting Commission, which is required to adjust the boundary lines of congressional, Senate, Assembly, and State Board of Equalization districts in each year ending in 1. If enacted by the Legislature and approved by the voters, ACA 8 of the 2025–26 Regular Session would adopt new congressional district boundaries that would remain in effect until the commission next adjusts the boundaries in 2031, if another state also adopts new congressional district boundaries between August 1, 2025, and January 1, 2031. If ACA 8 is enacted by the Legislature and approved by the voters, and a specified provision of that measure becomes operative, this measure would prohibit a Member of the Legislature who voted in favor of ACA 8 from being a candidate for congressional office in any congressional district adopted pursuant to ACA 8.
