Oregon State Senator Lee Beyer (D-Springfield) has introduced SB 328. Currently, Oregon holds its presidential primary and its primary for other office in May. The bill would keep the presidential primary in May, but would move the primary for other office to the third Tuesday of September.
The bill would have no impact on minor parties or independent candidates, because minor parties nominate by convention (except that the Independent Party will almost certainly nominate by primary in 2016). Also the petition deadline for newly-qualifying parties and independent candidates, which is in August, is not tied to the date of the primary. Thanks to Josh Putnam for this news.
