PoliticsEdit

Being home to a major population center and a major research university, Pima County is one of the most reliably Democratic counties in Arizona. After voting Democratic through 1930s and 1940s, it swung to Republican following major population increase after World War II, becoming a Republican-leaning county. However, in 1964, it rejected Arizona's native son Barry Goldwater by seven points, who won statewide by one point. However, despite the county's Republican lean, Democrats would not win 40% of the vote only twice - in 1972, when George McGovern lost in a 49-state landslide and due to a balloting error in the county, the Socialist Workers Party came a distant third with 18% of the vote;[28] and in 1980, when Jimmy Carter, being largely insensitive to Western states' issues, also lost many votes to independent John B. Anderson. Following Bill Clinton's plurality victory by 12 points in 1992, all Democrats since 1996 have won the county by a majority and no Republican has come closer than six points in recapturing the county. In both 2016 and 2020, Donald Trump became the first Republican since Bob Dole in 1996 to fail to win 40% of the county's vote.
