Openly bisexual actor Cynthia Nixon has announced she will run for governor of New York.

The Sex and the City star is challenging Andrew Cuomo for the Democratic nomination, ABC News has reported.

If elected, she would be both the first LGBTI person and the first woman to become governor of New York.

A statement by Nixon’s campaign said she was a progressive candidate.

“We want our government to work again, on healthcare, ending mass incarceration, fixing our broken subway,” said the statement.

“We are sick of politicians who care more about headlines and power than they do about us.

“It can’t just be business as usual anymore.”

A poll released yesterday showed Cuomo beating Nixon, with 66 per cent of registered Democrats saying supported him, compared to 19 per cent for Nixon.

Cuomo earlier this month joked about Nixon’s celebrity status.

“Normally name recognition is relevant when it has some sort of connection to the endeavour,” he said.

“If it was just about name recognition, then I’m hoping Brad Pitt and Angelina Jolie and Billy Joel don’t get into the race.”

Nixon tweeted an announcement of her candidacy.

“I love New York, and today I’m announcing my candidacy for governor,” she posted.

Reactions on Twitter have been mixed, with some New Yorkers welcoming Nixon’s announcement, and others saying that she should stick to entertainment.

“Hope we all learned not to make the same mistake twice #nomore #celebrities,” posted one person.

One wit tweeted, “Finally, a Nixon you can trust.”

Nixon received the Vito Russo Award at the 2010 GLAAD Media Awards, recognising “a significant difference in promoting equality for the LGBT community”.
