Michael Russnow is a California scriptwriter and recently an officer with the Writers Guild of America. He has worked on many well-known television series, and some films, and is a Democrat and a former congressional aide. He has this commentary on California’s top-two “open primary” system here.
He mentions the California June 2012 primary ballot, which lists 24 candidates for U.S. Senate. Having that many candidates in the primary season is not unusual in California. In 2010, there were 23 candidates on the various primary ballots for Governor. But, in 2010, no California ballot was crowded, because those 23 gubernatorial candidates were distributed on the separate primary ballots of six different political parties. The top-two system creates one large primary ballot for all seven of California’s qualified parties, so the system gives the appearance of lots of candidates.
California has fewer legislative candidates in 2012 than it did in 2010.
