Why did cartoonist thomas nast portray boss william tweed is a vulture feeding on the city of new york?

William Magear "boss" Tweed is a corrupt representative who defrauds millions of dollars from New Yorkers. He and his peers in the Democratic Party in New York exploit their power in the government for personal gain. As a civil reformer and a cartoonist, Thomas Nast portrays William Tweed as a vulture who preys on New Yorkers.
