However, a House-passed bill (HB 110) with an amendment to shift the date of the state presidential primary now sits in the Senate committee on Financial and Governmental Organizations and Elections. Like the Senate bill already in that same committee, the amended House bill would change the date of future presidential primaries from the first Tuesday after the first Monday in February to the first Tuesday after the first Monday in March (March 8 in 2016).
Interestingly, this House bill combines the primary move with some revisions to the language in the Missouri statutes dealing with vacancies to the general assembly and statewide offices. That was a combination that derailed the only bill that passed both chambers in 2011 and would have moved the 2012 Missouri primary to March (and into compliance with the national parties' delegate selection rules). Unlike the previously vetoed bill, the current legislation does not propose replacing the executive branch the ability to fill vacancies with special elections. Instead, that power still resides in the executive branch. The bill merely clarifies the gubernatorial power with respect to several statewide offices where there were gaps.
Governors and vacancies aside, legislation to shift the Missouri primary to March -- and presumably back into compliance with both national parties sets of delegate selection rules for 20161 -- has passed the Missouri House. The bill is not on the Senate committee hearing agenda at this time.
[A link to this legislation has been added to the 2016 presidential primary calendar here.]
1 That compliance issue is likely why there is as much legislative activity so early in Missouri to move the primary for 2016.
