DemocraticRepublican-controlled Senate.1 The bill is Republican-sponsored and just passed the Republican-controlled House, but obviously garnered bipartisan support. That is likely attributable to the fact that the legislation would bring the primary date into compliance with both national parties' delegate selection rules. Both parties, in other words, are on board with the move to March.
1 FHQ's go-to site for partisan control of state legislatures has been the National Conference of State Legislatures State Vote 2010 site. Unfortunately that is a static site and does not account for changes like the party switches in the Louisiana Senate since the first of the year.
