CA120: Voter registration is huge, partisan and volatile
Prior to the June Primary, California experienced a massive surge in voter registration. More than 2.3 million voters registered, either for the first time, or as a re-registration. This was not only larger than any other primary election in the state’s history, it was larger than any general election. As measured by absolute growth of the voter file, the nearest comparison was the 1980 primary in which former California Governor Ronald Regan was running for the Republican Party nomination.
