On July 13, California Governor Gavin Newsom signed SB 437, which requires qualified parties to notify the Secretary of State by 75 days before a presidential general election of the names of their presidential and vice-presidential nominees.
This is the type of law that is often administered in a discriminatory fashion. There have been times in some states when a major party failed to follow such a deadline, but state officials always excused these lapses. For example, in 1964, the Iowa Democratic Party forgot to certify Lyndon Johnson’s name in time, but the Secretary of State put him on the ballot anyway. Major parties have similarly sometimes missed these types of deadline in Indiana, Texas, and Florida, but always there were no consequences.
But when minor parties or independent candidates miss these deadlines, usually the state enforces the law. In 1996 the Arizona Libertarian Party missed a deadline, and the Secrertary of State refused to put Harry Browne on the ballot. But a state court reversed the action of the Secretary of State and put Browne on.
