Gov. Andrew Cuomo has sustained his lead over his Democratic primary challenger Cynthia Nixon, leading her by a 35-percentage point margin, according to a poll released Wednesday by Siena College.

The poll found Cuomo receiving 61 percent of Democrats poll, with Nixon at 26 percent. That’s a bump from April, when Siena found Cuomo leading Nixon 58 percent to 27 percent.

Cuomo’s leads over Nixon extend to virtually every demographic, the poll found. Cuomo leads Nixon among women, 63 percent to 26 percent and liberals by 65 percent to 24 percent. Cuomo is also handily defeating Nixon with suburban voters, 76 percent to 13 percent, as well as black voters, 74 percent to 17 percent and Latino voters, 69 percent to 23 percent.

The closest margin between the two is with voters upstate, were Cuomo leads 47 percent to 39 percent.

Democrats in general view Cuomo favorably by a 67 percent to 28 percent margin.

Cuomo and Nixon alike lead the presumptive Republican nominee, Dutchess County Executive Marc Molinaro, among likely voters, the poll found.

Cuomo leads Molinaro 56 percent to 37 percent. Nixon would best Molinaro, but by a smaller margin, 46 percent to 35 percent, according to the survey.

At this point in the election cycle in 2014, Cuomo was leading Republican Rob Astorino by a larger margin, 57 percent to 21 percent.

Molinaro remains largely unknown to likelty voters, with 71 percent unable to offer an opinion of him. Republicans have not won statewide office in New York since 2002, when Gov. George Pataki won a third term.

Cuomo’s favorability rating has not largely changed since April, when he recorded a 49 percent to 44 percent rating with registered voters. The poll released Wednesday found Cuomo at 51 percent to 44 percent in favorability among likely general election voters.

There’s no clear frontrunner, meanwhile, in the race for attorney general and the three Democratic candidates — Tish James, Zephyr Teachout and Leecia Eve — remain largely unknown to voters statewide. The poll was conducted before Rep. Sean Patrick Maloney declared he would enter the race.

Without Maloney, James received 28 percent of support, with Teachout at 18 percent and Eve at four percent.

The poll of 745 likely voters has a margin of error of 3.7 percentage points and was conducted from June 4 to June 7.

Updated: The Nixon campaign in a statement said the poll was bad news for Cuomo given his favorability rating and her improved numbers with younger and more liberal voters.

“The Governor’s team pulled out every trick in the book to try to improve his numbers,” said campaign spokeswoman Lauren Hitt.

“But, despite their efforts, the Governor’s unfavorability remains the highest it’s ever been, and Cynthia’s favorability dramatically increased among Democrats, liberals and young voters. That favorability will only continue to grow as the campaign tells voters more about Cynthia and her plan to create a New York that works for everyone.”
