In a national landslide for incumbent President
Lyndon B. Johnson,
Arizona was one of only six states carried by Arizona native and U.S Senator
Barry Goldwater, and the only state that Goldwater won outside of the
Deep South. Johnson successfully carried many Republican strongholds such as Alaska, Idaho, Indiana, Kansas, Nebraska, Oklahoma, North and South Dakota, Utah and Wyoming; however, he lost Arizona by 0.99% or less than 5,000 votes, the smallest margin of any state in the election. Arizona’s result was 23 percent more Republican than the country as a whole.
Key to Goldwater’s victory was
Maricopa County, the state’s most populated county, which he won by over twenty-one thousand votes, enabling Goldwater to carry the state despite Johnson winning ten of fourteen counties and two of three congressional districts. This is as of
the 2016 election the last occasion when
Yuma Counties have supported the Democratic candidate – indeed since 2000 Graham and Mohave counties have along with
Yavapai County – which has never given a Democratic majority or plurality since Truman in 1948 – been the most Republican in the entire state.
Since gaining statehood in 1912, Arizona had been considered a
bellwether state in elections. Indeed, the
previous presidential election was the first where the state did not back the winning candidate. This election, though, marked Arizona’s turn into a firm stronghold of the Republican Party. Starting in
1952 and continuing through
1992, Arizona would vote for the Republican candidate in every presidential election (mostly by relatively large margins, unlike Goldwater’s close victory), and it was the only state during those forty years not to vote for a Democrat at least once.
Bill Clinton would carry the state by a small margin in
1996, but his victory has proven to be an exception, as the state has continued supporting Republicans since.
