The constituency was represented by Gabrielle Giffords of the Democratic Party from January 3, 2007 and is considered a swing constituency. Giffords was assassinated during a public appearance in a shopping mall on January 8, 2012 and was seriously wounded. Her office manager and five other people were killed. Her successor was her chief of staff Ron Barber , who after the redesign of the constituencies, which gave Arizona an additional congressional electoral district with the 9th according to the 2010 census results , in future took up position in the 2nd district of Arizona, which geographically largely corresponded to the previous 8th.
For the 2012 election, the previous 2nd district, which largely covered the western suburbs of Phoenix, became the 8th district. With a Cook Partisan Voting Index of R + 13, it has a structurally much more republican-oriented electorate. The previous MP for the 2nd district, Republican Trent Franks , then ran in the November 2012 election in the new 8th district and won it easily, most recently in the 2016 election with almost 69 percent of the vote. After allegations that he had sexually harassed two employees, Franks resigned on December 8, 2017. There was an extraordinary by-election for this seat. In the primary on February 27, 2018, it was determined that Republican Debbie Lesko would run against Democrat Hiral Tipirneni in the main election on April 24, 2018. Although the district is Republican in character (Trump won the 2016 presidential election by 21 percent), the Republican National Committee invested over $ 280,000 in campaign support after a few weeks earlier in Pennsylvania's 18th congressional electoral district it had failed to become structurally clearly Republican To hold constituency (see Conor Lamb ). Lesko won by four percentage points.
