In summary

California’s citizens redistricting commission is designed to be nonpartisan, but party politics will be influenced by its final congressional and legislative maps. Most studies say Democrats will still have the upper hand.

Redistricting won’t change that California is a blue state. But it could decide just how blue it is.

For the second time, the once-in-a-decade process of drawing the state’s new congressional and legislative districts was in the hands of an independent commission — officially without concern about the impact on the partisan balance of power.

But in reality, party politics shadows the entire process — and the citizens commission got plenty of outside pressure.

And its final districts will nonetheless impact partisan dynamics — including whether Democrats are able to keep the supermajority in the Legislature they won in 2018 and retained in 2020. 

Heading into the 2022 elections, Democrats have a stranglehold on power in California: 59 of 80 seats in the state Assembly and 31 of 40 in the state Senate, plus 42 of 53 in the U.S. House.

The final districts aren’t likely to change those numbers much, according to a new study. Democrats are likely to keep 41 of 52 House seats, 62 Assembly seats and 31 Senate seats, says the Public Policy Institute of California analysis.    

Fredy Ceja, communications director for the commission, said that when seeking public comment, it didn’t ask for political affiliation. And he noted that the state constitution says that “districts may not be drawn for the purpose of favoring or discriminating against an incumbent, political candidate, or political party.”

State Senate and Assembly 

Democrats have a supermajority in the Legislature, and, under the maps, that doesn’t appear likely to change.

According to the PPIC analysis, which uses data from the nonpartisan PlanScore site, 12 Assembly seats and 7 Senate seats are likely to change party control at least once in the next decade — a decrease from the preliminary maps and current districts. 

The commission does not take into account the current district lines, or where incumbents live. That’s why the final maps place as many as 20 state Assembly members and 13 state senators in a district with another incumbent.  

Legislators would have to move to another district to avoid running against a fellow lawmaker, though enforcement of the law has been weakened. The final lines will also determine who can challenge incumbents and can run for open seats

One factor that is already influencing the potential partisan breakdown: legislators who are leaving voluntarily. Four have already resigned, and another 15 have announced they won’t seek reelection in 2022. They include 15 Democrats, 3 Republicans and the lone independent in the Legislature. 

Among them: Democratic Assemblymember Kevin Mullin of San Mateo County, who is seeking a U.S. House seat; Assemblymember Marc Levine of Marin County, who is running for insurance commissioner; and fellow Democratic Assemblymember Richard Bloom of Santa Monica, who is running for Los Angeles County supervisor.

Even with some departures, however, Republicans have no realistic hope of winning a majority in the Legislature. But getting rid of the Democratic two-thirds supermajority — which allows Democrats to pass tax increases or put constitutional amendments on the ballot without any Republican votes — is conceivably within reach. 

If Republicans were able to flip at least seven seats in the Assembly and five in the state Senate, they would have more influence over taxes and policy choices.

Democratic leaders shied away from commenting on the potential impact of the new districts while the commission is still at work.

“In keeping with the distinct roles established by voters for the Legislature and the Citizens Redistricting Commission, we will not be able to provide comment on the draft maps,” state Senate President Pro Tem Toni Atkins of San Diego and Assembly Speaker Anthony Rendon of Lakewood said in a joint statement provided Tuesday to CalMatters by a spokesperson. “While the Citizens Redistricting Commission does its job, the Legislature will continue to do ours — building upon the historic and transformative accomplishments that we have made in this legislative session.”

U.S. House

The stakes for California’s congressional seats could be higher, though not necessarily the competition.

According to the PPIC analysis of the final maps, 10 U.S. House seats are likely to change party control at least once in the next decade, compared to 10 within the existing districts.

Nationwide, Republicans only need to flip five seats in 2022 to take control of the U.S. House of Representatives. And they’re well on their way, just from the GOP-controlled redistricting already completed, according to analyses of new congressional districts by Politico and FiveThirtyEight.

That’s not by accident: In most other states, redistricting is done by state legislatures, most of which are under Republican control. That includes states that gained congressional seats after the 2020 Census, including North Carolina and Texas. (California lost a seat for the first time ever, complicating the redistricting process.)

In states where legislators drew the lines, nearly 90% of congressional races over the last decade were easy wins for one party or the other, Politico reports.

Jonathan Mehta Stein, executive director of California Common Cause, which has led the charge for independent redistricting commissions statewide and on the local level, noted that while the process has been “disruptive,” the alternative as seen in other states is a lot more gerrymandering and less competition.

The state’s redistricting commission isn’t supposed to consider where current elected officials live. And the preliminary maps put some House members and state legislators into less politically friendly districts, or in the same district as another incumbent.

California redistricting: Four key questions

California’s independent redistricting commission reaches a key milestone by releasing its preliminary congressional and legislative maps for public comment. But many changes are likely before final districts are adopted in late December for the 2022 election.
