context_page_description: The 2016 United States Senate election in Arizona was held on November 8, 2016, to elect a member of the U.S. Senate to represent the State of Arizona, concurrently with the 2016 U.S. presidential election, as well as other elections to the Senate in other states and elections to the U.S. House of Representatives and various state and local elections.
  The Arizona Democratic primary, 2016 was held on March 22, 2016, selecting Ann Kirkpatrick as the Democratic nominee. The Arizona Republican primary election took place on August 30, 2016.
  After serving in the Arizona legislature and U.S. House for a number of years, Kirkpatrick sought to unseat incumbent Republican Senator John McCain, who won re-election to his sixth and final term in office.
  After hinting in September 2013 that he could retire, McCain subsequently said that the chances he would run again were "pretty good", but his campaign had emphasized that he had not made a decision yet. On April 7, 2015, McCain announced that he would run for re-election. McCain faced strong primary opposition from the Tea Party, but he managed to defeat challenger Kelli Ward in the August 30 primary.

McCain faced strong primary opposition from the Tea Party, but he managed to defeat challenger Kelli Ward in the August 30 primary.
  McCain won with 53.7% of the vote compared to Kirkpatrick's 40.8%, with 5.5% voting for the Green candidate Gary Swing. Although McCain won reelection by double digits, this was the closest margin of his Senate career. 
  On August 25, 2018, Senator John McCain died of brain cancer, leading Governor Doug Ducey to appoint former U.S. Senator Jon Kyl to fill the seat. However, this action was taken with the understanding that Kyl would only serve until the end of the year. Rep. Martha McSally was selected as Kyl's replacement starting 2019, and is running in the 2020 special election to fill out the remainder of the term.
