New York City Mayor Bill de Blasio is officially running for president, defying deep voter opposition at home to enter the crowded field with an unabashed message of progressivism. De Blasio launched his website Thursday morning and made the announcement in a three-minute campaign video titled "Working People First." "There's plenty of money in this world. There's plenty of money in this country. It's just in the wrong hands," De Blasio says in the video, which touts his accomplishments bringing universal pre-K, paid sick leave and a $15 minimum wage to the city. "I'm running for president because it's time we put working people first." De Blasio refers to President Donald Trump as a "bully" and says he must be stopped. The president was quick to respond, tweeting early Thursday, "The Dems are getting another beauty to join their group."
