Around 10-20% of Californians have "Oakie" heritage (in reality from northern Texas mostly) from the Dust Bowl era.
Working class white Californians who I went to elementary school with in the Bay and Central Valley acted very similar and talk similar to Texans from Dallas-Waco-Austin area (heck, y'all is fairly commonly used in CA as is "heck")
> the emphasis has always been on the difference with Washington, D.C.
We do the same when the GOP comes to power.
