On July 13, Arizona Governor Jan Brewer signed SB 1074, another omnibus election law bill. The only ballot access implications in SB 1074 are that the bill moves the non-presidential primary from 9 weeks before the general election, to 10 weeks. Therefore, in 2010, Arizona will hold its primary on August 24, the earliest non-presidential primary in Arizona history.
The date change means that the non-presidential independent candidate deadline moves a week earlier, to May 26. There is no logical reason why the independent candidate petition deadline is keyed to the date of the primary, but in Arizona, that is how it is done. The petition to recognize a party also moves a week earlier, to March 4.
