Several bills have been introduced in the Oklahoma legislature to move the non-presidential primary from the last Tuesday in July, to the last Tuesday in June. They are SB 602, HB 1615, and HB 2138. These bills also all move the deadline for the petition for a newly-qualifying party from May 1 to March 1.

A petition deadline of March 1, for new parties, is very likely to be held unconstitutional. Similar deadlines for new parties have been held unconstitutional in Alabama, Alaska, Arkansas, Indiana, Kentucky, Maine, Massachusetts, Nebraska, Nevada, New Jersey, Ohio, Pennsylvania, South Dakota, and Tennessee. Thanks to Richard Prawdzienski for the news about these bills.

The difference between HB 1615 and HB 2138 is that the latter bill also moves the presidential primary from February to March. Besides that bill, there are two other bills that move the presidential primary date, but do not move the date for the non-presidential primary. They are SB 808 and HB 1614. Thanks to Josh Putnam for the news about those latter two bills.
