Over the course of a decade, from 2006 to 2016, a Latino-led movement in Arizona’s Maricopa County fought Sheriff Joe Arpaio and his local immigration crackdowns. American citizens of Latino descent, who felt targeted by Arpaio’s immigrant roundups, joined a movement to gather evidence against the sheriff in a landmark racial profiling lawsuit. Federal courts later found that the sheriff’s tactics were unconstitutional. The Latino-led resistance contributed to Arpaio’s electoral loss after 24 years in office. It also helped transform Arizona into a battleground state in the 2020 election.
