Although Arpaio sought another term as Maricopa County Sheriff in 2016, the contempt of court conviction eroded much of his remaining political support, and he was defeated in the election by Paul Penzone, a Democrat who reversed many of Arpaio's policies after taking office. Arpaio was an unsuccessful candidate in Arizona's Republican primary election for U.S. Senate in 2018. On August 25, 2019, Arpaio issued a statement saying that he would run for sheriff of Maricopa County in 2020. He lost the August 2020 primary election.
