Who was the leader of the political machine that controlled new york in the late 1800s using birbery and intimidation?

Your answer is: William Marcy "Boss" Tweed

The leader of the  Democratic Party political machine that pretty much controlled New York.
It wasn't an ACTUAL machine, just so you know, but rather it was an organization that took control through bribing and intimidating people, digging up dirt, etc.
