(CALMATTERS) – Today, the independent commission charged with redrawing California’s legislative and congressional districts every 10 years is set to hear public comment on its draft Assembly maps — a process it will repeat Friday for its proposed state Senate maps. When drawing new districts, the commission isn’t supposed to consider how incumbents might be affected — in fact, it isn’t even supposed to know where elected officials live. But California politicians are well aware of what new district boundaries could mean for their careers. And, with a Tuesday study finding that 20 members of Congress, 29 state assemblymembers and 14 state senators have been drawn into districts already occupied by another incumbent, the stakes for the June 2022 primary election are high, CalMatters’ Sameea Kamal reports.

“It does create kind of a frenetic, potentially very expensive, potentially very nasty … primary.”

To make matters even more confusing, only half of the 40-member state Senate is up for re-election in 2022. That means the new maps could result in some Californians having two senators — or none at all — living in their districts between 2022 and 2024. Sameea breaks down what it all means.
