There are 53 congress members from California. The districts have been gerrymandered so completely that it is almost impossible to win an election against an incumbent. Seven of the districts have no opponent on the ballot.
My own district 30 has had a Democratic congressman as long as anyone can remember. Actually West Los Angeles has had a democratic representative since at least 1956. You thought I live in the San Fernando Valley and you are correct. The district has been renumbered and stretched to ensure that a Democrat is always easily elected. It is still a district that covers Beverly Hills and West Los Angeles.
Why does this gerrymandering continue? The state legislature controls the district geography and those legislators have reached an agreement on dividing up the control of the districts. An article in the Los Angeles Times says that this is the result of influence of Nancy Pelosi. “She wouldn’t trust the fate of Democratic seats in California to a bunch of citizen noncombatants.”
