I don't think suburban Southern California is swinging hard to the GOP in wake of Dobbs. Especially not the Thousand Oaks area nor the Ventura area.
My grandmother lives in Thousand Oaks (a very swingy white part of CA-26). Politically, it seems remarkably stable due to the relative abundance of older people and the area generally being less transient. The people who live there generally stay there for a long time.
Brownley is not in any immediate danger; if she loses Dems are already losing like 60+ seats.
Indeed, those are the not the sort of areas Democrats are losing ground in. The inclusion of areas like Porter Ranch and Granada Hills are why I think CA-27 is overrated for the Republicans. Even if they gain a lot of ground in the Antelope Valley, they will not do well in those suburban areas.
