My mom still lives in CA 48, Rohrabacher's old district. To say the switch over isn't a big deal is pure bull. The 48th is/was prime Reagan country but also home of John Wayne and a long tradition of GOP and hardline cold war warriors...not to mentioned a bunch of Birchers, Christian kooks (Crystal Cathedral) and wing nuts.
The one commonality might be level of education and I think that's the basis of the flip...educated people don't swallow horse pucky by the gallon, and women were fed up and po'ed. They looked the other way for economics for a long time but Trump ended that, as did the Russkies. Educated people tend to stop and ask questions, like if Rohrabacher is a Russkie asset and tool. Trump didn't help nor did Kavanaugh.
Also Issa's seat in CA 49 flipped and that's just as big of a deal given it borders southern OC and SD is more conservative then OC and includes Camp Pendleton.
Flipping 48 and 49 were big deals. Both were as solidly GOP as SF is Dem. Imagine if SF flipped...that's how big of a deal it is.
I'm assuming you make this stuff in the Dajo vain.
Maybe you should talk to your mom some more to get you facts straight.
Rohrbacker has not lost yet nor has the race been called. He probably losses but it will be real close. The District may be full of wing nuts since it voted for Obama and Clinton, and has a higher Dem registration than GOP registration. The District boundaries have changed a lot (in fact Issa was once the Congressman), but it never included (and is not geographically close) to the Crystal Cathedral. The District was not even rated red (Cook toss-up, Sabato's toss-up, and Inside Elections blue). Your thinking is decades old and full of stereotypes. Just like SF flipping. Yes, maybe 1950 SF flipping.
As for 49, it was a District, when created , that was held by 2 Democrats and a Republican, before Issa, who was gerrymandered out of the 48th (don't tell Dajo). The 49th District had then been gerrymandered to isolate all the GOP votes in one district so it included conservative portions of the Inland Empire and inland northern San Diego County giving Issa a strong base. But in 2012, the District was redrawn to take out the conservative inland areas, to include a small portion of very southern OC and the San Diego coast all the way down to La Jolla. Your talking the few SC cities that mostly voted for Obama and Kerry, and to the extent there are liberals in San Diego county, they are in these beach cities. Issa didn't run because he knew a Democrat would win. Again, this is not even close to your SF flipping scenario. I don't know where you get this cr@p.
