went back and checked back to 1996 (there's 1992 data as well but hella blurry)

2008: none

2004: brentwood, clayton, danville, atherton, hillsborough, dixon, rio vista, vacaville

2000: livermore, pleasanton, clayton, danville, moraga, san ramon, belvedere, atherton, hillsborough, woodside, los altos hills, saratoga, dixon, rio vista, vacaville

(livermore, pleasanton, brentwood, and moraga were very close, brentwood went blue by five votes)

1996: clayton, danville, martinez, san ramon, belvedere, atherton, hillsborough, woodside, los altos, los altos hills, monte sereno, saratoga, rio vista
