2018 Arizona's 8th congressional district special election

A special election for Arizona's 8th congressional district was held in 2018 subsequent to the resignation of Republican U.S. Representative Trent Franks. Governor Doug Ducey called a special primary election for Tuesday, February 27, 2018, and a special general election for the balance of Franks' eighth term for Tuesday, April 24, 2018.

Republican nominee and former Arizona Senate president pro tem Debbie Lesko won a closer-than-expected race against Democratic challenger Hiral Tipirneni.

Background
Incumbent representative Trent Franks announced on December 7, 2017, that he would resign effective January 31, 2018, after admitting allegations regarding the issue of surrogacy. However, after his wife was hospitalized, Franks resigned effective December 8, 2017.

Candidates must file nomination forms and petitions within 30 days of the governor's proclamation. Candidates in special congressional elections in Arizona must collect a number of valid signatures equal to at least one-fourth of 1% of the number of qualified signers in the district. For the 2018 special election, a Democratic candidate requires 665 signatures, a Green candidate requires 392 signatures, a Libertarian candidate requires 401 signatures, a Republican candidate requires 860 signatures, and an independent candidate requires 4,680 signatures.

It was initially thought that Arizona's resign-to-run law would have required sitting members of the Arizona Legislature to resign their seats in order to run in the special election. Arizona's resign-to-run law does not require someone to resign if they file to run when they are in the final year of their term. However, the deadline to submit nominating petitions was January 10 and the end of the current term for members of the Arizona Legislature was January 14, 2019. However, legal advice from the legislature's nonpartisan counsel stated that incumbent state legislators would not be required to resign in order to run in the special election.

Republican primary
Two of the major candidates in the Republican primary drew controversy late in the campaign. Former state senator Steve Montenegro faced calls to withdraw, including by former governor Jan Brewer, after news articles revealing sexually suggestive text messages between Montenegro and a legislative staffer surfaced. Additionally, complaints were filed against former state senator Debbie Lesko over her campaign finance records.
