Clinton’s California advantage over Sanders: Her allies living in your neighborhood

Be rnie Sanders is winning the visuals in the fight for California's presidential vote. Every one of his events draws enthusiastic crowds numbering in the adoring thousands, demonstrating support that he hopes will translate into momentum. Hillary Clinton ’s campaign events are by design more intimate, featuring hundreds of supporters in venues selected  to show her personal side.

But that visual contrast is only one — and historically not a determinative — measure of support. Another is the house-by-house, community group-by-community group warfare being waged in a far less visible way across the state.

In that, Clinton has the advantage, with her army of elected officials and other elements of the Democratic establishment, all trying to persuade their supporters to side with the front-runner.
