In 2018, Arizona held a general election on November 6 that determined statewide offices, U.S. congressional seats, state legislative seats, and ballot measures. This overview explains how results were finalized, key races and margins, the role of provisional and mail ballots, and how official records are maintained. Outcomes reflected broad participation and shifts in party control across several contests. Below, verified details define what happened, when, and where to confirm results for research or civic purposes.
How Results Were Defined and Certified
Election results in Arizona are certified by county election officials and then by the Arizona Secretary of State after canvassing. Canvassing consolidates vote counts, confirms eligibility, and resolves discrepancies such as provisional ballot review. Certification timelines vary by year and race complexity, but final results are typically certified within weeks of the election. Legal deadlines govern challenges and recounts, ensuring transparency and accuracy. Understanding this process helps distinguish official outcomes from preliminary or unofficial numbers reported on election night.
Key Steps in Certification
- County canvass and consolidation of early, mail, and in-person votes
- Provisional ballot verification and adjudication
- Statewide canvass and certification by the Arizona Secretary of State
- Public audit processes and documentation retention
Notable 2018 Races and Verified Outcomes
In Arizona’s 2018 general election, several high-profile races set records for turnout and spending. U.S. Senate, Class I; all of Arizona’s seats in the U.S. House; half of the state senate; and all state house seats were on the ballot. Gubernatorial, secretary of state, attorney general, and superintendent of public instruction contests drew significant attention. Ballot measures addressed topics such as education funding and healthcare. Verified results reflect the formal vote count after certification, including candidate vote totals and margins.
Certification Timeline and Key Dates
| Date or Period | Event | Why It Matters |
|---|---|---|
| November 6, 2018 | General Election Day | When voters cast ballots for federal, state, and local offices |

Verified Results and Margins
Official results list candidate names, party affiliation, vote totals, and margins for each race, as submitted by counties and reviewed by the state. Close races may trigger recounts or audits under state law. Ballot measures require a specified percentage of yes/no votes to pass or be referred for further action. Because Arizona uses a mixed voting system that includes extensive mail voting and early voting, many ballots are counted after Election Day, which can affect when final margins are confirmed.
Sample Outcome Patterns (Illustrative)
- U.S. Senate: Incumbent wins reelection or challenger wins, with margin verified after canvass
- U.S. House: All Arizona districts decide seats based on certified results
- State Legislative: Partisan composition shifts based on certified margins
- Ballot Measures: Passage determined by vote thresholds defined in state law
Provisional and Mail Ballot Processes
Arizona elections feature extensive use of mail and provisional ballots, which are processed after Election Day. Provisional ballots are reviewed for eligibility before being counted, and voters may cure certain deficiencies. Mail ballots must be received by a deadline and verified for signature and postage. These steps ensure accuracy and legitimacy but can delay final results compared to in-person election night counts. Understanding this workflow clarifies why some results take days or weeks to become official.
Where to Find Official 2018 Results and Records
Verified 2018 results are maintained by the Arizona Secretary of State and available through official election result archives. County election offices also keep records of ballots processed, turnout by precinct, and post-election audits. Researchers and the public can access these materials for historical analysis, civic education, or compliance purposes. When reviewing data, prioritize official government sources over unofficial aggregations to ensure accuracy and context.
