(CNN) - A new poll indicates that New York's two incumbent Democratic senators are leading their Republican challengers by double digits.
According to a Marist College Institute for Public Opinion survey released Tuesday, Sen. Kirsten Gillibrand tops Joseph DioGuardi, her GOP opponent, 52 to 41 percent among likely voters, with seven percent undecided.
Gillibrand's advantage in the Marist poll is wider than a six-point advantage she held over DioGuardi among likely voters in a Quinnipiac University survey released Thursday.
The Marist survey shows Gillibrand holding a 46 to 41 percent advantage over DioGuardi among independent voters. About two-thirds of voters in New York City back Gillibrand, with voters in New York City's suburbs and upstate divided.
"The seat is leaning Gillibrand's way," says Marist pollster Dr. Lee Miringoff. "But the contest remains competitive."
Gillibrand, a former upstate congresswoman, was named to replaced Sen. Hillary Clinton early last year after Clinton stepped down to become secretary of state.
DioGuardi is a former congressman and the father of former American Idol judge Karen DioGuardi. The winner in November will serve out the final two years of Clinton's term.
In the New York's other Senate contest, the poll indicates that two-term Sen. Chuck Schumer leads his little known GOP challenger Jay Townsend 58 to 37 percent among likely voters, with five percent undecided.
The Marist College Institute for Public Opinion poll was conducted September 19-22, with 915 registered voters, including 617 likely voters, questioned by telephone. The survey's sampling error for likely voters is plus or minus four percentage points.
