Born to a RINO (RR) father I guess he went full on liberal.
His great grandfather, Hamilton Fish II, was the Speaker of the New York State Assembly and a member of the United States House of Representatives, also a Republican.
His grandfather, Hamilton Fish III, served in the United States House of Representatives from 1920 to 1945 and he too was a Republican.
His father, Hamilton Fish IV, was a Congressman from New York, and a Republican
He, Hamilton Fish V or Jr., ran unsuccessfully for Congress in 1988 & 1994, as a Democrat.
Hamilton Fish II was a hero and a member of the Rough Riders who died in Cuba from a gunshot wound.
Both Fishes stank like they were rotten.
Was it his grandfather who was an ardent opponent of FDR?
