Once forgotten, a California primary could sway 2016 contest

California's primary amounts to 54 separate races on a single day — one in every congressional district across the sprawling, diverse state, and one statewide. The winner in each district collects three delegates; then, the candidate who gets the largest number of votes statewide claims a bonus of 13 more.
That means a solidly Democratic district covering the heavily Hispanic neighborhoods east of downtown Los Angeles has the same importance as one in the traditional Republican heartland of Orange County, once the home of Richard Nixon.
