Oct. 6 marks the beginning of the voting period for California’s Proposition 50 special election , which asks voters whether to implement new, partisan congressional maps for the 2026, 2028, and 2030 elections.

If Prop. 50 passes, California would forgo the current maps drawn by a 14-member group comprising five Republicans, five Democrats, and four commissioners not affiliated with the two major parties. Instead, new maps would favor Democrats in California’s congressional elections as a way to counter similar, Republican-led plans elsewhere in the country to boost the GOP.

If you’re having trouble visualizing what, exactly, that could look like, these interactive maps help show both the big-picture, statewide changes and the changes to your own congressional district.
