Middlesex County is governed by a Board of Commissioners, which is comprised of seven members who are elected at-large on a partisan basis to serve three-year terms of office on a staggered basis, with either two or three seats coming up for election each year as part of the November general election. At an annual reorganization meeting held in January, the board selects from among its members a Commissioner Director and deputy director. The Commissioner Director appoints commissioners to serve as chairpersons and members on the various committees which oversee county departments. Middlesex County also elects three "constitutional officers" whose existence is laid out in the New Jersey Constitution.

Accessed February 9, 2022. "Middlesex County Sheriff Mildred Scott, a Democrat, was elected in 2010, making her the first African-American woman to be elected sheriff in New Jersey, and the first woman sheriff in Middlesex."

After being a Republican stronghold in the late 19th and early 20th centuries, Middlesex County leaned Democratic for much of the 20th century beginning with Franklin Roosevelt's victory in the county in 1932. Throughout the twentieth century, in close elections, the county would always vote Democratic, sometimes by solid margins, but the county was willing to flip Republican in the midst of nationwide Republican landslides in the 1970s and 1980s. Since 1992, the county has always voted Democratic, however, the 2024 election saw the Democratic margin held to the single digits for the first time since 1992. As of August 1, 2020, there were a total of 545,795 registered voters in Middlesex County, of which 229,982 (42.1%) were registered as Democrats, 84,258 (15.4%) were registered as Republicans and 224,058 (41.1%) were registered as Unaffiliated. There were 7,497 (1.4%) voters registered to other parties.{{Cite web|title=NJ Voter Registration by County|url=https://nj.gov/state/elections/assets/pdf/svrs-reports/2020/2020-08-voter-registration-by-county.pdf |archive-url=https://web.archive.org/web/20200920183502/https://nj.gov/state/elections/assets/pdf/svrs-reports/2020/2020-08-voter-registration-by-county.pdf |archive-date=September 20, 2020 |url-status=live|website=NJ DOS - NJ Division of Elections}}
