Historical composition of the Suffolk County Legislature

Republicans controlled the county legislature until a landmark election in November 2005 where three Republican seats switched to the Democrats, giving them control. In November 2007, the Democratic Party once again retained control over the Suffolk County Legislature, picking up one seat in the process. In November 2009, the Republican Party regained the seat lost in 2007 but remained in the minority for the 2010-2011 session. In November 2011, the Democratic Party maintained control over the Suffolk County Legislature picking up one seat that had been held by an Independence Party member. In November 2013, the Republican Party gained the 14th district seat, but remained in the minority until 2021, when the GOP flipped the county legislature, picking up three seats with incumbents Robert Calarco (the sitting Presiding Officer) and Susan Berland (the sitting Majority Leader) losing their bids for re-election. During the 2020-2021 session, 7th district legislator Robert Calarco served as Presiding Officer, a position he was elected to in 2020, 5th district legislator Kara Hahn served as Deputy Presiding Officer. 18th district legislator William Spencer served as Majority Leader for the Democrats until his arrest for soliciting prostitution in a drugs for sex scandal.

Secessionist movements

At various times, there have been proposals for a division of Suffolk County into two counties. The western portion would be called Suffolk County, while the eastern portion of the current Suffolk County would comprise a new county to be called Peconic County. Peconic County would consist of the five easternmost

towns A town is a human settlement. Towns are generally larger than villages and smaller than cities, though the criteria to distinguish between them vary considerably in different parts of the world. Origin and use The word "town" shares an ori ...

of Suffolk County: East Hampton, Riverhead, Shelter Island,

and Southold, plus the Shinnecock Indian Reservation. The proposed Peconic County flag showed the two forks at the east end of Long Island separated by Peconic Bay. The star on the north represents Southold. The stars on the South Fork represent Southampton and East Hampton. Riverhead is at the fork mouth and Shelter Island is between the forks. The secessionist movement has not been active since 1998. ''The End of the Hamptons: Scenes from the Class Struggle in America's Paradise'', by Corey Dolgon (New York University Press, 2005) examined the class roots of the secessionist movement in the Hamptons. In his review,

Howard Zinn Howard Zinn (August 24, 1922January 27, 2010) was an American historian, playwright, philosopher, socialist thinker and World War II veteran. He was chair of the history and social sciences department at Spelman College, and a politica ...

wrote that the book " kes us beyond the much-romanticized beaches of Long Island to the rich entrepreneurs and their McMansions, the Latino workers, and the stubborn indigenous residents refusing to disappear. The book is important because it is in so many ways a microcosm of the nation." The book won the Association for Humanist Sociology's 2005 Book Prize and the American Sociological Association's Marxist Section Book Award in 2007. Matt DeSimone, a young adult from Southold, started a similar movement in the late 2010s. With partner Jake Dominy, also of Southold, they made hats promoting the secessionist movement. It went nowhere.
