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.
