Cynthia Nixon, an activist and actress best known for her role as Miranda Hobbes in HBO’s Sex in the City, announced on Monday that she is running for governor of New York. She’ll be challenging incumbent Gov. Andrew Cuomo, who is seeking his third term, in the Democratic primary. The New York Times calls it a “huge undertaking,” given Cuomo’s political experience, his family legacy (his father Mario Cuomo was a three-term governor of New York), and his campaign war-chest of over $30 million. While in some ways Nixon is a political neophyte — she has never run for, or held office before — the actress has been politically active on specific issues, including education, LGBT rights, and women’s rights for years. Here’s what you need to know about Cynthia Nixon. I love New York, and today I'm announcing my candidacy for governor.
