Succession Mechanics for U.S. Senate Vacancies
How Senate Vacancies Are Filled
The U.S. Constitution grants each state primary authority to determine how to fill Senate vacancies. Arizona follows a process where the governor appoints a replacement, subject to election at the next general ballot. The appointee serves until a special or regularly scheduled election convenes, ensuring the seat is never left vacant for long.
Key Dates in McCain’s Senate Succession
| Date | Event | Why It Matters |
|---|---|---|
| August 25, 2018 | John McCain passes away | Senate seat and related duties become vacant |

| December 31, 2018 | Jon Kyl resigns from Senate | Triggers another appointment process |
| January 3, 2019 | Governor Ducey appoints Martha McSally | McSally serves until special election results finalize |

Who Directly Replaced McCain in the Senate
The person who first replaced John McCain in the Senate was Jon Kyl, appointed temporarily to maintain institutional continuity. Kyl served for a brief period before resigning for personal reasons. He was followed by Martha McSally, who was appointed to continue representation until Arizona held a special election. Kyrsten Sinema eventually won that election and became the elected successor for the remainder of the term.
Jon Kyl’s Appointment and Brief Tenure
Jon Kyl, a former Arizona congressman and longtime public servant, accepted an interim appointment to fill McCain’s seat. His service emphasized protocol and continuity, providing experienced legislative support during a sensitive transition. Kyl’s resignation highlighted the voluntary nature of interim service and the importance of aligning appointments with voter preference through timely elections.
Martha McSally’s Appointment and Service
Martha McSally, a retired military pilot and former state senator, was appointed to serve after Kyl. Her tenure focused on representing Arizona’s interests while awaiting the outcome of the special election. McSally’s appointment demonstrated the state’s capacity to deploy qualified leaders during interim periods.
Elections and the Long-Term Replacement
After interim appointments, Arizona held a competitive special election to determine the long-term occupant of McCain’s seat. The process allowed voters to choose representation aligned with their preferences. The outcome reflected the evolving political landscape of the state while honoring the duty of continuous governance.
2020 Special Election Results
The 2020 special election was closely watched as a indicator of broader trends. Kyrsten Sinema’s victory marked a shift in the state’s Senate representation, moving from interim appointments to an elected leader chosen directly by Arizona voters. This transition reinforced democratic processes and the importance of timely electoral resolution.
McCain’s Roles Beyond the Senate
While the question of Senate succession is central, John McCain also held roles that required separate consideration. His influence on foreign policy, military affairs, and national discourse left a void that extended beyond legislative seats. Understanding replacements in these spheres involves looking at institutional and cultural influence rather than formal succession.
Legacy and Institutional Influence
- Bipartisanship: McCain was known for crossing party lines on key votes, shaping outcomes independent of office.
- National Security: His long career informed defense debates and policy consultations.
- Advocacy: McCain supported veterans, prisoner-of-war issues, and ethical governance.
These aspects of his work are not replaced by a single person but continue through institutions, successors, and the ongoing engagement of civic actors.
Broader Implications of Senate Succession
Succession processes ensure that governance remains stable even amid unforeseen departures. They reflect constitutional design, state preparedness, and the commitment to representative democracy. The McCain case illustrates how planned transitions preserve continuity while engaging the electorate at every stage.
