Oklahoma was won by incumbent United States Vice President George H. W. Bush of Texas, who was running against Massachusetts Governor Michael Dukakis.

[1] The Southeastern portion of the state resumed turning out in large numbers for the Democratic Party; in 1984 almost all its counties voted in majority for Reagan.

Bush's dominance in the more populated metro Oklahoma City and Tulsa ensured a safe GOP victory.

Additionally, this remains the last time that a Democrat has won more than sixty percent of the vote in any Oklahoma county (these being Jefferson, Haskell, Hughes, Coal and Choctaw).
