Missouri Governor Jay Nixon (D) today issued a call for a special session of the state legislature to convene on September 6.1 Republican leadership in the legislature received their preferred date for the start of the session, and the resulting session will overlap with the legislature's September 14 veto session. The proclamation calls for the date of the presidential primary to be addressed moving the nomination contest to the first Tuesday after the first Monday in March (March 6, Super Tuesday).
In other words, we will likely know within that first week -- give or take a few days -- whether General Assembly Republicans will pursue the call for a "clean" bill regarding the presidential primary or move to override the governor's veto. The latter would require the help of four Democratic representatives to be successful.
Theoretically, Missouri should fall in line fairly soon after Arizona Governor Jan Brewer (R) makes the decision on when the presidential primary in the Grand Canyon state will be. If January 31 is the date Governor Brewer is intent on that decision will have to be made -- via proclamation -- on or before September 2.
