 While in Suffolk County, the Republican Party had long since taken back the Town of Brookhaven in 2012 as well as the Town of Islip in 2011 and flipped control of the Town of Huntington in 2017.The Democratic Party did win the Supervisor seats in both the Town of Hempstead and the Town of Riverhead in 2017, but those gains reversed back to the Republican Party in 2019, while the Supervisor of the Town of Shelter Island reversed from a Republican gain in 2017 back to a Democrat gain in 2019.The Towns of Smithtown and Oyster Bay have consistently maintained Republican majority for several decades, and the Towns of North Hempstead and Babylon have similarly been dominated by Democratic majorities for several decades.
