Union County (Spanish: Condado de la Unión) is the northeasternmost county in the U.S. state of New Mexico. As of the 2020 census, the population was 4,079,[1] making it the fourth-least populous county in New Mexico. Its county seat is Clayton.[2] The county was formed in 1894.[3] Union County borders Colorado to the north, and Oklahoma and Texas to the east.

History[edit]

Union County, was created by an act of the territorial legislation in 1893 and was officially recognized on January 1, 1894, when the first slate of elected county officials received their oaths of office. The county is named “Union” because the citizens were united in their desire for the creation of a new county out of three existing New Mexico counties. Union County was subsequently “carved up” by the creation of additional counties, Quay in 1903 and Harding in 1920. At one time, Union County had a population of over 20,000. There were a number of bustling communities such as Amistad, Hayden, Sedan, Pasamonte, Gladstone, Mt Dora, Grenville, Des Moines, Folsom, and Dedman (now known as Capulin).

Politics[edit]

Like all of Eastern New Mexico, Union County is heavily Republican. The county has not voted for a Democratic presidential candidate since 1948. Hillary Clinton in 2016 received the worst showing for a Democrat in the county's history – but this was partially due to a large migration towards third-party candidates such as New Mexico native and former governor Gary Johnson, who ran as a libertarian. In 2020, Donald Trump went on to receive the best performance for a Republican in the county's history.
