As these cases makes their way up through the courts, Arizonans across the state will continue to do the work of having conversations about why marriage matters and creating a climate for victory.


In November 2006, a proposed anti-marriage constitutional amendment was rejected at the ballot in Arizona. With this, Arizona became the first state to reject an anti-marriage constitutional amendment, by a margin of 52 percent to 48 percent.

In November 2008, however, anti-gay forces in Arizona pushed through an anti-marriage constitutional amendment that excluded same-sex couples from marriage.

Several jurisdictions, including Bisbee and Tucson, have passed protections for domestic partners.


In Arizona, a majority of voters support the freedom to marry for same-sex couples, with 55% saying they support marriage, and just 35% saying they oppose marriage (Behavior Research Center, September 2013). A separate poll found that 79% of Hispanic respondents approve of marriage for all couples. (Public Policy Polling, May 2012)
