This week, voters affirmatively passed Proposition 50, a congressional redistricting plan. What does Prop 50 do?
This measure replaces the current congressional map with new districts. California has 52 congressional districts; voters in each district elect a member of the U.S. House of Representatives to represent them in Congress.
On August 21, Gov. Gavin Newsom signed Assembly Bill 604, which provided for new congressional district boundaries for California. However, AB 604 cannot take effect without voter approval of Proposition 50, which is an amendment to California’s state constitution. This constitutional amendment was put forward by the California State Legislature in partnership with Newsom via Assembly Constitutional Amendment 8 (Robert Rivas and Mike McGuire).
Democrats have argued their push is necessary to counter Republican-led gerrymandering in states such as Texas. Redistricting Partners, LLC — based in Sacramento, CA — drafted the congressional district map that the legislature adopted.
California joins more than a dozen states making moves to redraw congressional district lines. However, it is one of the only states to give voters the opportunity to vote on the measure. Nonetheless, this action is a departure from the state’s previous practice of employing a nonpartisan voting commission to draw district lines.
The nationwide trend to redraw congressional district lines is unprecedented. Typically, states update redistricting plans after each U.S. census to account for population shifts among various regions. However, President Donald Trump has encouraged Republican states to pursue redistricting plans to increase the margin of Republicans in Congress. In four states, Republicans have implemented new congressional maps, which target nine sitting Democratic members of Congress.
Proposition 50 adjusts the political makeup of voters in five congressional districts that lean Republican. New congressional district lines shift these congressional seats to lean Democratic. Lines were redrawn based on presidential election results in 2024. Presidential candidate Kamala Harris would have won three of the new congressional districts with margins over 10 percent. Those districts include:
The two remaining districts lean more Democratic, which affects the following sitting members of Congress:
Trump would have won these districts with a margin of 2 percent, but it will make the races in these congressional districts more competitive. The existing district lines of Rep. Young Kim (R-CA-40) will be changed as well. Specifically, California Congressional District 40 will be a district with voters from Rep. Kim’s (CA-40) and Rep. Ken Calvert’s (CA-41) districts, making it a stronger Republican district.
However, now two incumbents may face each other in a congressional race. Calvert has announced he will run in CA-40, which is the district Kim currently represents.
How does this all impact credit unions? Existing relationships with congressional offices will likely be adjusted in 2026, with some incumbents likely to lose their seats. This means credit union advocates will invest time meeting candidates for new congressional seats. Early in the process, California’s Credit Unions will ask credit union advocates to tell the story of the credit union difference and share the mission of “people helping people.”
Unfortunately, some credit union champions are at risk of losing their seats. However, California’s Credit Unions is committed to supporting candidates who believe in the difference credit unions make in their communities.
