2020 Arizona elections

Elections were held in the U.S. state of Arizona on November 3, 2020, as part of the 2020 General Election. Arizona voters chose 11 electors to represent them in the Electoral College via a popular vote. Three seats on the Arizona Corporation Commission were up for election, as were all nine of Arizona seats in the United States House of Representatives, and one of its seats in the United States Senate. Primary elections were held in August 2020. Paper ballots for voting by mail were sent to all registered voters in the state.

U.S. President
Arizona was represented by 11 electors in the electoral college. Joe Biden won the state with 49% of the popular vote. This was the first time a Democratic presidential candidate won Arizona since Bill Clinton in 1996.

U.S. Senate
A special election was held due to the death of Republican senator and presidential candidate John McCain.

Former U.S. senator Jon Kyl was originally appointed to the seat, but resigned on December 31, 2018. Outgoing U.S. Representative Martha McSally was appointed to fill the seat following Kyl's resignation.

Democrat Mark Kelly defeated McSally, winning 51% of the vote.

U.S. House of Representatives
All nine of Arizona’s seats in the United States House of Representatives were up for election in 2020. Before the election, Republicans held four seats and Democrats five. No districts changed hands, and thus Democrats maintained control.

Corporation Commission
Three seats on the Arizona Corporation Commission were up for election. Republican Bob Burns was term-limited and therefore ineligible to run for re-election to a third term in office.

Polling
Each voter selected up to three candidates in the state Corporation Commission general election, with the top three vote-getters winning the seats. Consequently, poll results in the table immediately below are displayed as the accumulation of a candidate's first, second and third preferences, and therefore total 300%, instead of 100%. Where a given percentage of voters are not decided with respect to multiple choices, that percentage is multiplied by the number of choices for which they are undecided (so, for instance, if 1% of voters had not picked any candidate, they would be listed in the table below as 3% of the total vote).

Ballot initiatives
Two initiatives were approved for the general election ballot.

Proposition 207
Proposition 207, the Smart and Safe Arizona Act, is to legalize and tax cannabis for adult use.

Proposition 208
Proposition 208, the Invest in Education Act, is to impose a 3.5% income tax surcharge on high earners and invest the revenue generated in education.
