ALBANY -- Sex and the City star Cynthia Nixon continues to explore a run for New York governor this year.

Nixon has been weighing a Democratic primary run against Gov. Andrew Cuomo in September, and a report Tuesday suggested she is laying the groundwork for a run.

But a spokeswoman would only say Nixon, who has been active in New York politics for years, continues to explore the possibility.

"Many concerned New Yorkers have been encouraging Cynthia to run for office, and as she has said previously, she will continue to explore it," Rebecca Sides Capellan, Nixon's spokeswoman said.

"If and when such a decision is made, Cynthia will be sure to make her plans public."

Cuomo says whom he wants as his running mate

Nixon is one of at least three Democrats considering a challenge against Cuomo, who is seeking a third term in November and is a potential 2020 presidential candidate.

Former Syracuse Mayor Stephanie Miner is contemplating a primary challenge to the Democratic governor, while former Hudson Valley Sen. Terry Gipson already launched one.

NY1 reported Tuesday that Nixon is poised to jump into the race, saying she is assembling a staff that includes former advisors to New York City Mayor Bill de Blasio, who is a Cuomo political foe.

But several progressive groups working to find a candidate to challenge Cuomo said Tuesday they were unaware of any looming decision by Nixon.

"We’re hoping that somebody comes forward, and we’re hoping that either Stephanie or Cynthia Nixon run, but neither one has indicated to us that they are near a decision," Arthur Schwartz, an organizer for the New York Progressive Action Network.

Last August, Nixon said on the Today show that, "There are a lot of people who would like me to run. And I think for a variety of reasons, but I think the No. 1 is education."

She went on to knock Cuomo's record on school aid, saying education funding is something "parents all across New York state talk to me about."

Cuomo's office countered at the time that the governor has provided record aid to school since taking office in 2011.

On Tuesday, Cuomo sounded unmoved by Nixon's potential candidacy.

"On people who may or not run for governor on both sides of the aisle, we'll deal with that as it progresses," he told reporters.
