According to a new poll out on Monday, three contenders are within striking distance of each other in the hard-fought race for New York State attorney general, a position that has the potential to be a bugbear for the Trump administration.

The poll by Siena College also found that Gov. Andrew M. Cuomo continues to hold a commanding lead over his Democratic primary opponent, Cynthia Nixon. Mr. Cuomo has a 41-point advantage over Ms. Nixon ahead of Thursday’s vote, 63 percent to 22 percent, according to the poll.

The race for attorney general appears to be far more competitive, with Representative Sean Patrick Maloney leading the field with 25 percent of the vote, followed closely by Letitia James, the New York City public advocate, who has the support of 24 percent of those polled. Zephyr Teachout, a law professor, placed third in polling, with 18 percent, and Leecia Eve, a former Clinton administration aide and a Verizon executive, had only 3 percent.

The poll reflects the opinions of 509 likely voters who are New York State Democrats, and was conducted over four days last week, before a pair of headaches for the governor, including the delayed opening of a marquee project — the Mario M. Cuomo Bridge, across the Hudson River — and a heavily criticized flier from the state Democratic Party that implied Ms. Nixon was anti-Semitic.
