On September 6, the Michigan State Appeals Court reversed the lower court and construed Michigan law to let Robert F. Kennedy, Jr., withdraw from the ballot. Kennedy v Secretary of State, 372349. There is a law that has a restrictive and discriminatory deadline for minor parties to withdraw earlier than major parties. But the Appeals Court said that restrictive law, saying Kennedy should have withdrawn in August, only applies to candidates for state office, not federal office.

16 states successfully withdrawn at last count.
