Democrats have commanding leads in two US Senate races in New York, but the race for attorney general is closer, according to a Quinnipiac poll of likely voters.

Kirsten Gillibrand leads former GOP congressman Joe DioGuardi, 55-34 percent. That's up from the 48-42 percent race that Quinnipiac had in their poll two weeks ago.

Chuck Schumer leads Republican Jay Townsend 63-32 percent, with 65 percent of respondents saying they don't know enough about Townsend to have an opinion.

In the attorney general's race, Democratic State Senator Eric Schneiderman leads Republican District Attorney Dan Donovan 43-32 percent. Another 24 percent of voters remain undecided.

Donovan leads Schneiderman among independent voters, 36-30 percent. Schneiderman narrowly leads Donovan among upstate voters, 37-35 percent, (which is within the poll's 2.9 percent margin of error), and nearly splits the suburban vote, 40-39 percent.

Schneiderman's biggest leads is among New York City voters, where he leads Donovan 54-24.

In the state comptroller's race, incumbent Tom DiNapoli (who was appointed to the position and has not run statewide before) leads his Republican rival, Wall Street financier Harry Wilson 49-31 percent.
