Arizona law sets the 2012 presidential primary on February 28, but the law also gives the Governor the authority to change that date. On July 21, Arizona Governor Jan Brewer suggested she is inclined to move the primary into January. See this story. Thanks to Frontloading HQ for the link.
Although press stories focus on the impact this would have on the Republican presidential contest, the proposed early Arizona primary could also impact the Libertarian Party and the Green Party. Both are entitled to a presidential primary in Arizona if they desire one. In 1996, the Arizona Libertarian Party and the Arizona Democratic Party won a court order, saying that if a party doesn’t want the state to hold a presidential primary for itself, then the state should respect the party’s wishes and not hold one. Republicans also refused a presidential primary in Arizona in 2004. Arizona held no presidential primaries before 1996.
In 2008 the Libertarian Party declined to participate in the state’s presidential primary, but held its own party-financed mail presidential primary. The Arizona Green Party has never before been entitled to participate in a government presidential primary. Although the Green Party successfully petitioned to be a qualified party in 2000 and 2008, it didn’t qualify in time for its own presidential primary. For 2012, however, the Greens are already qualified so they could have their first presidential primary if they wish to.
