Alameda (East Bay) went 78.7% to Clinton plus another 6.6% to third parties
Santa Clara (South Bay) went 72.2% to Clinton plus another 7.2% to third parties
San Francisco went 85.0% to Clinton, with another 5.7% to third parties
So yeah, painting a picture of three people of different economic backgrounds, it would not be illustrative to make even one of them a supporter of the current regime.
