Suffolk County’s Republican machine was dominated by Klan members in the 1920s.

Evidence

The baymen’s land-locked cousins, the farmers of Long Island, were men of conviction, too. In no part of New York State were the white hoods of the Ku Klux Klan, an organization whose venom was directed in the 1920’s not only against Negroes but also against Jews and Catholics, as numerous as in Suffolk County. Three successive chairmen of Suffolk’s Republican Party had been members of the Klan, and anyone who needed an additional symbol of its power had only to look at the flagpole in front of the Islip Town Hall: the pole, read the inscription on an attached plaque, had been donated by the Islip branch of the Ladies of the Klan and gratefully accepted by the Town Board. (In 1928, when Al Smith ran for President, fiery crosses would blaze on the hills of Alabama and Mississippi—and, by orders of the county GOP organization, on the hills of Suffolk.) Combining with the baymen to dominate the Suffolk political picture, the farmers had no difficulty persuading the county’s supervisors to make sure that there was not a single park in Suffolk open to city residents. — Robert A. Caro, The Power Broker, 648

Categorization

• XREF: Links to the larger story of how local roadblocks shaped the exclusion of city residents from Long Island parks—context for why Moses needed the state park authority to circumvent local boards.
• ADDENDUM: Parallel to the later Parkways/Long Island park building chapters where Caro describes the county elites’ anti-city bias as a deliberate obstacle Moses had to outmaneuver.
• QUESTION: Worth verifying whether the county GOP-Klan link here is corroborated by other histories of New York Republican politics in the 1920s.
