Actress and activist Cynthia Nixon, best known as one of the stars of HBO's hit series "Sex and the City," is launching a progressive primary bid against incumbent New York Governor Andrew Cuomo. 

"I love New York. I’ve never lived anywhere else. But something has to change.," she says in her announcement video. "We want our government to work again, on healthcare, ending mass incarceration, fixing our broken subway. We are sick of politicians who care more about headlines and power than they do about us."

A Siena College poll out Monday showed Nixon as a heavy underdog in the primary matchup, with Cuomo getting 66 percent support among registered Democrats, compared to just 19 percent for Nixon.
