The notorious racist former Arizona Sheriff Joe Arpaio has announced he is running for Senate in the race to replace retiring Republican Senator Jeff Flake. Arpaio has been a major supporter of President Trump, who pardoned the ex-sheriff last year, after he was convicted of contempt of court for defying an order to stop his deputies from racial profiling. For years Arpaio ran a notoriously racist sheriff’s department in Maricopa County, Arizona. He once bragged that he ran his open-air tent city jail like a “concentration camp.” Arpaio was first elected in 1992 and was voted out of office in 2016 after Latinos organized a massive get-out-the-vote campaign.
