Former Sex and the City star Cynthia Nixon has bigger things on her mind than the Sarah Jessica Parker-Kim Cattrall feud: she's running for governor of New York.

Nixon announced on Twitter Monday that she will seek the Democratic nomination in this fall's gubernatorial race, challenging incumbent Mario Cuomo in the primary. She posted a powerful video detailing her history as a resident of New York as well as a the current failures in local government like healthcare, mass incarceration and the broken subway system she plans to correct.

Nixon had long been rumored to be considering a gubernatorial run as a progressive candidate. "We have to be more than the anti-Trump party," she said at the annual Human Rights Campaign Greater New York gala in February. "In 2018, we don't just need to elect more Democrats, we also need better Democrats."

The actress has no political experience, but that's not a barrier to entry to high-level political office anymore.

Nixon is best known for playing Miranda on the HBO comedy series Sex and the City from 1998 to 2004 and in the 2006 and 2010 movies. She's also played two first ladies, Eleanor Roosevelt and Nancy Reagan. Nixon got more involved with political activism as the show wound down and heavily campaigned for New York mayor Bill de Blasio in 2013 and has been a vocal advocate for LGBTQ rights.

As a candidate, the New York City icon will face one simple question from New Yorkers that can make or break her campaign: can she actually fix the trains?
