Otero County, New Mexico: History
The western part of Otero County was handed over to the United States Army as the US was preparing to enter World War II and eventually became part of White Sands Missile Range. This did not significantly hinder the growth of the county, whose population more than doubled in the 1950s.
The county declared a state of emergency in April 2019 when the federal inspection stations on U.S. Route 70 and U.S. Route 54 were left unstaffed by U.S. Customs and Border Protection as part of the temporary closure of all six checkpoints in the El Paso Sector, which covers West Texas and New Mexico. The county was concerned about the possibility of illegal narcotics flowing north unchecked since the checkpoint agents had been shifted to the border to help process migrant asylum-seekers. The inspection stations reopened August 5, 2019.
On Monday June 13, 2022, the county commissioners attracted nationwide attention by refusing to certify the results of the local 2022 primary election on June 7, 2022. In response, the New Mexico Secretary of State filed a lawsuit and writ of mandamus against the commissioners for their refusal. By Friday June 17, 2022, two of the three commissioners agreed to certify the election results, which defused the crisis.
