On June 15, the Louisiana Senate & Governmental Affairs Committee voted to defer HB 509. Because the legislature adjourns in a week, this action severely injures the bill, although it could still be revived. HB 509 moves the presidential primary from February to March. If Louisiana does not move its primary out of February, the national Democratic Party rules, and the national Republican Party rules, if enforced, will cost the state half its delegates to the national conventions. See this story.
The major party rules do not permit any presidential primaries or caucuses earlier than March, except for Iowa, New Hampshire, Nevada, and South Carolina.
