House remained in Republican control, with 33 Republicans to 27 Democrats. During his term as governor, Castro was heavily criticized by Republicans, who believed that Castro simply wanted to have the title of governor, rather than actually perform the duties involved with holding the office. Columnist John Kolbe of the Phoenix Gazette wrote about Castro, saying "Covering the amiable and peripatetic chief executive has become a newsman's jungle of half-completed sentences, imprecise factual data, and even contradictory assertions." While serving as governor, Castro campaigned in the 1976 presidential election for former Georgia Governor Jimmy Carter, despite this, Gerald Ford won Arizona. Castro also campaigned for Carter in New Mexico and Texas. Resignation, U.S. Ambassador to Argentina Facing growing criticism during his term as Governor of Arizona, including sustained opposition from the state legislature, Castro was offered the position of U.S. Ambassador to Argentina under President Jimmy Carter, in 1977. Arizona Secretary of State Wesley Bolin succeeded Castro as governor, following his resignation, but Bolin would die in office less than a year into his term. Castro was ambivalent about resigning from the office of governor, not wanting to let down the Hispanic community that had helped to elect him to the position. However, Castro would later state that he felt he would be of greater help to the Hispanic community, serving in the capacity of U.S. Ambassador to Argentina. Castro again faced adversity during his time as Ambassador, due to his Mexican heritage, with many Argentinians questioning why the United States would select a Mexican to serve in Argentina. Castro served in the position from 1977 to 1980, and would be the last time that Castro would serve in political office. Honors In 2007, Castro's alma mater, now known as Northern Arizona University, named the home of the College of Social and Behavioral Sciences in his honor. As a student, he competed in track and boxing for the school; he was inducted into the Northern Arizona University Athletics Hall of Fame in 1988 and into the College of Social and Behavioral Science Hall of Fame in 2011. Detainment by Border Patrol On June 12, 2012, on his birthday, Castro was detained by agents of the United States Border Patrol for a half hour while being driven as a passenger in a car to a birthday celebration from his home in Nogales, Arizona to the Mountain Oyster Club in Tucson, Arizona.
