(CNN) – Republican Gov. Jan Brewer toed the party line Monday, signing a proclamation that set Arizona's primary date for February 28, according to a statement from her office.
Brewer had threatened to move the state's primary up to January 31 in an effort to give Arizona greater influence in the GOP presidential nominating calendar.
But that move would have directly violated Republican National Committee rules that forbid any state other than Iowa, New Hampshire, Nevada and South Carolina from holding a primary or caucus before March 6 and set off a chain reaction forcing those states to move their primaries up.
Brewer announced in early September that Arizona may be a staging ground for an officially sanctioned primary debate and hinted she wouldn't hold the primary in January, but left the possibility of moving the date up from its originally scheduled date in late February.
RNC spokesman Sean Spicer confirmed, "The debate committee tentatively sanctioned a debate pending a formal proposal from Arizona that meets the guidelines of the debate committee and receives their approval."
And though Brewer skipped the deadline to claim January 31st as her date of choice, the proclamation makes her decision for Arizona's primary to stay put official–while still shaking up the calendar and defying RNC rules. South Carolina's primary is scheduled for February 28 as well, and officials have indicated they will move it to January if Arizona's is held on that day.
