In addition to the Oklahoma bills detailed earlier today, there is a more all-encompassing election law bill (HB 2138) that shifts the date of the Sooner state's primaries for state and local offices from July to June, changes filing deadline and also alters the presidential primary date, moving the election from the first Tuesday in February (where the state's presidential primary has been since the 2004 cycle) to the first Tuesday in March. From 1988-2000 Oklahoma held its presidential primary on the second Tuesday in March. The Democratic Party in the state used the same date for its 1984 caucuses.
The bill is sponsored by Republican Rep. Kris Steele and is the third bill that has been introduced including a provision to move the presidential primary back to March.
