William "Bill The Butcher" Poole, the inspiration for the character portrayed by Daniel Day-Lewis in Gangs of New York, 1875.
The anti-foreign, anti-Catholic, and anti-immigrant “Native American” political party was formed in 1843. (At the time, the phrase “Native American” referred to people born in the U.S. and NOT to the indigenous people of the country.) William Poole (the basis for the character “William Cutting” in the movie “Gangs of New York”) was a member of the New York branch of that organization (which was often called the “Know Nothing” Party). He was also the head of his own West Side gang.
The Native Americans used Poole as their chief “enforcer.” As a butcher in real life, Poole (wielding the knife of his trade) could accurately hit a target from 20 feet. He had served an “apprenticeship” with the Bowery Boys, was known to gouge out the eyes of his foes, stood more than six feet and weighed more than 200 pounds.
He, and members of his gang, had special jobs to do for the Nativists on election days: commandeer votes. It is said that they stood outside polling places with bludgeons in their hands. Sometimes they forced people to vote more than once. They sought to elect candidates who would guard against “foreigners” getting jobs they believed should go to native-born Americans.
