The 9th circuit will hear Nader v Brewer on April 15. This is an Arizona ballot access case. The issues are whether states may ban out-of-state residents from collecting signatures for an independent candidate, and whether states can set the independent presidential petition deadline in early June.
Arizona has the state’s 2nd earliest independent presidential petition deadline. Only the Texas deadline is earlier. The Arizona deadline is so early, it is three months before the state’s primary, and also three months before the date of the Republican National Convention this year.
