Gerrymandering can only go so far. If your overall vote is running anywhere from 75% to 85% for the bad guys, you’re not going to get a competitive district out of it. Take a look at another example of a moonbat state, Massachusetts. Of the 10-member House delegation, we couldn’t gerrymander for ourselves a single Republican seat. At best, we might be able to get one in which we have a 40%+ shot at winning, but no better. San Francisco, Marin, San Mateo, Alameda, most of Contra Costra — they’re virtually all out of reach now.
Remember, too, that the post-2002 Congressional lines in CA are effectively little changed from the post-1992 lines, essentially incumbent protection, which were favorable to the GOP (and at one point, we had a tied delegation in 1995 following Tom Campbell’s special election victory, 26 seats each). Aside from a couple seats, virtually all the counties that vote majority GOP do have GOP Congressmembers.
Also, San Diego has a Republican mayor(Sanders) but a Democratic congress rep(Davis). Hunter’s district is only the suburbs and not SD proper.
