[Ed. – Same story as in many places in 2018, including much of “suddenly blue” Orange County (CA). The retiring Republican incumbent won by 26 points in 2016.]
The House seat has been held by a Republican for all but one term since 1968.
Donald Trump, the Republican nominee for president, won the district by 10 points over Democrat Hillary Clinton in 2016.
On election night, media outlets called the race for [Republican] Herrell, 54, who has been a member of the New Mexico House of Representatives since 2011.
But well after midnight, Harrison said, the office of New Mexico’s secretary of state informed the Herrell campaign of 4,000 absentee ballots in Doña Ana County still to be counted, which would not have flipped the race to Torres Small, who previously had not held elective office.
However, the state informed the campaign of another 4,000 absentee votes that had been counted but not tabulated, which was enough to change the outcome.
