## Politics

As of 2017, only Irion County among those in Texas had stated it would refuse to issue licenses to same-sex couples. Many counties started issuing same-sex marriage licenses within hours of the Obergefell ruling on June 26, 2015, while others awaited direction from state officials, local county attorney advice, or issuance of corrected state marriage license forms. Irion County adopted this reason for not issuing licenses. No marriage applications have yet been made by same-sex couples in Irion County. Irion County was the sole holdout in Texas, with reports that the situation was still in effect two years later. When Alabama replaced marriage licenses with marriage certificates and required that all counties issue them, Irion County became the only remaining county in the country that would not allow same-sex couples to marry. As of 2020, Irion County has a new county clerk who has stated she would issue marriage licenses to same-sex couples.
Irion County was one of four Texas counties Ross Perot won in the 1992 presidential election. Otherwise, the county, like most of rural Texas, is extremely Republican. It has not voted for a Democratic presidential candidate since Texas native Lyndon B. Johnson won a statewide and national landslide in 1964.
