The elections coincided with other federal and state elections, including a quadrennial presidential election, and a U.S. Senate election. Primary elections were held on August 28, 2012.[1]
Arizona was one of five states in which the party that won the state's popular vote did not win a majority of seats in 2012, the other states being Michigan, North Carolina, Pennsylvania, and Wisconsin.
