[4][5][6] The Arizona Republican Party played key roles in attempts to overturn the results of the 2020 United States presidential election[6] and the 2022 Arizona gubernatorial election.

[8] Republicans held both of the state's U.S. Senate seats between 1995 and 2019, and the governorship for all but six years between 1991 and 2023.

Appointed in 2019 by Governor Doug Ducey after the resignation of Jon Kyl who was appointed to the seat after the death of John McCain in 2018, McSally lost the 2020 special election to determine who would serve the remainder of the term expiring in 2023.

McSally lost the special election to Democratic challenger Mark Kelly, who won a full term in 2022, defeating Blake Masters.

John McCain is the last Republican elected to represent Arizona in the U.S. Senate in 2016, while Jeff Flake is the last Republican to represent Arizona for a full term in the U.S. Senate from 2013 to 2019.
