Who selects the Arizona electoral college?

Answer 1

The political parties in each state choose slates of potential Electors sometime before the general election. On Election Day, the voters in each state select their state's Electors by casting their ballots for President. The electoral college Electors in most states are selected by state party conventions or by the state party's central committee. In a few states the Electors are selected by primary election or by the party's presidential nominee. Political parties often choose Electors that are state elected officials, state party leaders, or people in the state who have a personal or political affiliation with their party's Presidential candidate. Democratic and Republican electors in Arizona in 2016 were chosen by the chairmen of state political parties.
