Again absolutely anecdotal but Sanders has a campaign branch opened last year in my town which confused the hell out of me, we're the poorest city of the county but population wise we're larger than the next two largest cities put together. Normally branches are opened in the two more affluent towns near by or Santa Baraba or Thousand Oaks in the next over counties. Most of our town however is Spanish speaking. That said, the guy's staff has literally shown up at church and neighborhoods just out of the blue constantly. Literally have never had my parents talk about a candidate till this year which is just fucking wild, they normally don't give a single flying fuck. The Spanish language outreach effort regardless of what you think of Sanders should absolutely be lauded and considered going forward.
