Carruthers served as a White House Fellow at the Department of Agriculture from 1974-75. A Republican, he was elected the 27th governor of New Mexico in 1986. A major focal point of the race was reinstating the death penalty, resulting in outgoing Democratic governor Toney Anaya commuting the sentences of all inmates on death row in protest.[5] His term ended in 1991, and term limits at the time prevented New Mexico governors from seeking consecutive terms. Carruthers was succeeded by Democrat Bruce King, who had previously served two non-consecutive terms as governor.
After leaving office, he served as founding president and CEO of the Cimarron Health Plan, now Molina Healthcare of New Mexico, Inc., from 1993 to 2003.[1] In 2003, he was named dean of NMSU's College of Business. He helped establish NMSU's economic development operation, the Arrowhead Center, and served as the university's vice president for economic development. He also helped establish the Domenici Institute and serves as its director.[6] In May 2013, he was appointed president of New Mexico State University by the Board of Regents in a 3-2 vote.[7] In 2017, the Board of Regents announced that his contract would not be renewed, resulting in his retirement effective July 1, 2018. He was succeeded by John D. Floros, a food scientist and former dean of the Kansas State University College of Agriculture.[8][9]
Views on science
Questioned by faculty at an on-campus meeting on his candidacy to become NMSU chancellor in 2013, Carruthers said that there was not a scientific consensus on climate change, stating "I don't know. I'm an economist. I don't do global warming. It's a scientific judgment that I can't make."[10] Concerns were also raised about his role in the Advancement of Sound Science Center, a lobbying group that he chaired from 1993 to 1998.[11]
