California has now reached an historic high of over 21 million registered voters. The current PDI voter file, after a full refresh of county files, puts total voter registration at 21,086,077. As a share of eligible voters, this puts the state at 83%, a higher rate of registration than we have seen since the presidential election of 1940.

ANALYSIS: Pew Research recently released a report titled Commercial Voter Files and the Study of U.S. Politics, which initially looked like a really interesting piece for someone like me who works in voter files every day.
