California's non-partisan election highlights a busy primary Tuesday this week. Also on the calendar, with more traditional primaries, are Alabama, Iowa, Mississippi, Montana, New Jersey, New Mexico and South Dakota. Nominees will be chosen for five Senate and five gubernatorial races across the eight states. California (and New Mexico) have elections for both.
The video below, from the Los Angeles Times, provides an overview of California's top-two primary system. All candidates appear on a single ballot. The top two vote-getters, regardless of party, move on to the general election. The most closely-watched races that might be impacted are three Republican-held congressional districts in Orange County and the state's gubernatorial race.
