A new Siena College poll suggests New Yorkers still prefer Governor Andrew Cuomo over the Democrat's current challengers in this year's election.
That's down from 66% to 19% last month before Nixon declared her candidacy.
It also comes at a time when Mr. Cuomo, a second-term Democrat who has been mentioned as a possible presidential contender, is being seen favorably by less than a majority: 49 percent.
A month after Nixon entered the Democratic gubernatorial race, Cuomo now leads the "Sex and the City" actress among registered Democrats by a 58% to 27% margin, according to the poll.
Nixon has gained ground since announcing her bid for governor last month, the Siena College survey found.
Nixon, however, has narrowed the race in the month since she officially joined the campaign for the Democratic nomination, he said.
"Early on, Cuomo seems to be in a strong position to again be the Democratic Party's standard bearer", Greenberg said. John DeFrancisco - Cuomo held leads of more than 20 percentage points. "In a variation of Bette Davis' famous line: Fasten your seatbelts; it's going to be a bumpy ride".
Greenberg pointed out Cuomo four years ago won the Democratic primary against Zephyr Teachout with 63 percent of the vote when only 11 percent of Democrats voted.
Fifty-seven percent of respondents give Cuomo a negative rating for his job performance as governor, the poll found.
Nixon, who is chasing after liberals in the Democratic Party, was unknown by almost half of registered Democrats, Siena said.
And while Cuomo continues to do well in New York City, his overall favorability numbers are under water in the suburbs and upstate.
Ms. Nixon's campaign, which has already garnered ample news coverage with calls for legalizing marijuana and tough attacks on Mr. Cuomo, got a major boost on Saturday when she received the endorsement of the Working Families Party, a small but influential progressive group.
The poll of 692 registered voters was conducted from April 8 to April 12.
