Bills have been introduced in each house of the Mississippi legislature to move the presidential primary (and the primary for all other office in presidential years) from the second Tuesday in March, to the first Tuesday in March. They are SB 2531 and HB 933. It is likely that when the Alabama legislature convenes, a similar bill will be introduced in that state. Both states had their presidential primaries on March 13 in 2012, but if the bills pass, they will be March 1 in 2016. For 2016, the major parties do not permit any states (except New Hampshire and South Carolina) to hold presidential primaries earlier than March 1. Thanks to Josh Putnam for the news.
