Man, I can't even imagine what a Republican from Walnut Creek or Concord really looks like. Probably easy to pick out of a crowd.... or not because there's so few of them.
Definitely a dying breed and general live out in wealthy mansions in the hills or a handful of senior citizen center, or are in deep undercover mode at their neighborhood BBQs in the middle class suburbs.
What some on this forum used to refer to as "Reagan Democrats" and key to the Bush Senior win in'88 and core to Pete Wilson scene.
Not sure if you ever spent time down in Cupertino, where I lived for awhile, but I think there might be a
few more Republicans in Concord and Walnut creek than much of South Bay, although it's difficult to poll with such a small subsample. Bet on for November when precincts report?
Either way a landslide in the Bay Area Region (BAR), and OC and SD counties aren't going to be much help propping up the margins this time around, when there is huge turnout in LA and Inland Empire combined with Central Valley and Sac.
I think 65-35 is a pretty realistic number... maybe even worse depending upon how the Trump trainwreck continues to roll.
