Politics

Maricopa County has a long history of being a Republican Party stronghold. While the city of Phoenix leans towards the Democratic Party, along with some other small areas within the county, the rest of it tends to vote heavily Republican, making it one of the more conservative urban counties in the country. Every Republican presidential candidate has carried Maricopa County since 1948. This includes the 1964 presidential run of native son Barry Goldwater, who would not have carried his own state had it not been for a 21,000-vote margin in Maricopa County. It is currently the largest county in the country to vote Republican. Since 1964, Democrats have only kept the margin within single digits three times–in 1992, 1996, and 2016.

Despite its apparent political leanings, Maricopa County voted against Proposition 107 in the 2006 election. This referendum, designed to ban gay marriage and restrict domestic partner benefits, was rejected by a 51.6–48.4% margin within the county, and statewide by a similar margin. Two years later, however, a majority of county residents voted to pass the ultimately successful state constitutional amendment banning same-sex marriage. The amendment was later overruled by the Supreme Court's 2015 ruling in Obergefell v. Hodges, which declared that same-sex marriage is a fundamental right in the United States.
Unlike cities and towns in Arizona, counties are politically and legally subordinate to the state and do not have charters of their own. The Board of Supervisors acts in the capacity of executive authority for the county within the statutes and powers prescribed by Arizona state law. The state legislature devotes considerable time to local matters, with limited discretion granted to the Board of Supervisors on minor ordinance and revenue collection issues. Chair of the Board is held by one member for a period of one year, and is selected by the Board members themselves through public hearing.
The County Sheriff, County Attorney, County Assessor, County Treasurer, Superintendent of Schools, County Recorder, Constables, Justices of the Peace, and Clerk of the Superior Court are all elected by the people. Retentions of Superior Court Judges are also determined by popular vote.
The county's dominant political figure for over two decades was Sheriff Joe Arpaio, who had dubbed himself "America's Toughest Sheriff" and gained national notoriety for his flamboyant and often controversial practices and policies.
As Maricopa County is home to almost 60 percent of the state's population, it dominates Arizona's politics. For example, in the 2018 Senate election, Democrat Kyrsten Sinema carried the county en route to becoming the first Democrat to win a Senate seat in Arizona since 1988. She won the county by over 60,000 votes, which would have been more than enough to give her the victory; she won statewide by 55,900 votes. Eight of the state's nine congressional districts include at least some portion of the county, and five of the districts have their population center located there. Most of the state's most prominent elected officials live in the county as well.
