The Common Sense Party is trying to qualify in California. Its website says it has 20,415 registered members, as of April 11. Back on February 18, the Secretary of State’s Report of Registration showed the party had 10,859 registered members, so it appears the party is actively working to increase its registration.
If its registration rises to .33% of the state total (not counting “unknown party” registrants) by July 6, 2020, it will be able to place a presidential nominee on the November 2020 ballot.
No one can know exactly how many registrations will be needed by July 6, because the base for the percentage is the number of registered voters (not counting unknown voters) as of that date, which of course, is in the future. Generally it is not good policy for a ballot access requirement to be based on a future piece of data, because this means the group can’t know what the requirement is, until it is too late to meet it. But of course the group can estimate. It is estimating 67,000 or so.
California residents can register on-line, or can change their registration from one party to another on-line, so that makes it possible for the party to be increasing its registration even in the health crisis. No new party has qualified in California via a registration drive since 1995, when the Natural Law Party and the Reform Party qualified. Both of them have since lost their qualified status.
