From an article on Richard Winger’s Ballot Access News website:
Irregular Times has this story, revealing that Americans Elect has begun its petition to qualify as a party in California. The petition requires 1,030,040 signatures. California has two methods to create a new party, either that it persuade a number of voters equal to 1% of the last gubernatorial vote to register into that group on voter registration forms, or to submit a petition signed by 10% of the last gubernatorial vote.
If the 10% petition were the only alternative, the law would have been declared unconstitutional long ago. The U.S. Supreme Court and lower courts have struck down all petition requirements for minor and new parties, and independent candidates, that are in excess of 5% of the number of registered voters. Such lawsuits were won in Arkansas, Illinois, North Carolina, Ohio, and South Dakota. But the 10% California law has survived because it is not mandatory. The 1% registration method can always be used instead.
