Explanation:

As of October 2020, California officially recognized six political parties: the American Independent, Democratic, Green, Libertarian, Peace and Freedom, and Republican parties.Although there are dozens of political parties in the United States, only certain parties qualify to have the names of their candidates for office printed on election ballots. In order to qualify for ballot placement, a party must meet certain requirements that vary from state to state. For example, in some states, a party may have to file a petition in order to qualify for ballot placement. In other states, a party must organize around a candidate for a specific office; that candidate must, in turn, win a percentage of the vote in order for the party to be granted ballot status. In still other states, an aspiring political party must register a certain number of voters. In some states, a candidate may choose to have a label other than that of an officially recognized party appear alongside his or her name on the ballot. Such labels are called political party designations. California does not allow candidates to use political party designations.
