On August 18, the California Secretary of State released a new voter registration tally. See it here. The tally is as of July 7. The previous tally had been as of May 23, just prior to the June 7 primary.
The number of registered voters increased to 18,084,999. The deadline for a new party to qualify for the presidential election was July 7. The law requires registration of .33% of the state total, on the deadline day. Until this new Report of Registration was released, it had been impossible to know exactly what the requirement was: 59,681 registrations. The California legislature eased that requirement in 2014; the old requirement had been registration equal to 1% of the last gubernatorial vote. The 59,681 requirement is thus the lowest registration requirement for a new party to qualify for the presidential election since 1964, when it was 59,297.
Notwithstanding that this was the lowest number of registrations needed since 1964, no new party qualified in California this year.
The percentages for the July 7 tally are: Democratic 45.10%; Republican 27.09%; American Independent 2.52%; Libertarian .645%; Green .435%; Peace & Freedom .39%; miscellaneous unqualified parties .54%; independent voters 23.29%.
The percentages for the May 23 tally had been: Democratic 44.82%; Republican 27.29%; American Independent 2.55%; Libertarian .643%; Green .435%; Peace & Freedom .40%; miscellaneous qualified parties .55%; independent voters 23.32%.
Between these two tallies, Constitution Party registration increased from 288 to 310. Reform Party registration declined from 11,946 to 11.835.
