(CNN) - Democratic nominee Cory Booker maintains his 12 percentage point lead over Republican rival Steve Lonegan one week before Election Day, according to a poll released Wednesday.
The Quinnipiac University survey shows Booker, mayor of Newark, has a 53%-41% lead among likely New Jersey voters over Lonegan, former mayor of Bogota, in the special Senate race held to fill the remainder of the term of late Democratic Sen. Frank Lautenberg.

The poll results remain unchanged from a Quinnipiac survey taken two weeks ago. The latest poll was conducted after the two candidates faced off in their first televised debate on Friday, and the survey's release comes hours before the two men debate for a second and final time.
A month ago, Booker had a much wider lead over Lonegan, by as much as 35 percentage points. The two Quinnipiac polls in the last two weeks, as well as a recent Monmouth University survey, show his lead has narrowed to about 12 points.
While each candidate carries an overwhelming majority of their respective party's voters in the new survey, Lonegan has more support among independents, 50%-44%. But with New Jersey being a state where Democrats vastly outnumber Republicans, Booker is still on top.
The new poll also comes after Booker made headlines for having private Twitter exchanges with an exotic dancer, a story that the candidate essentially shrugged off. His relationship with the dancer failed to rise to the level of scandal that engulfed former Rep. Anthony Weiner, or other politicians caught sending unexpected messages online.
Despite Booker's Twitter dust-up, women support the Newark mayor over Lonegan by a huge margin of 62% to 31%, while men back Lonegan over Booker, 51%-44%.
Three-quarters of women find the exotic dancer story a non-legitimate issue in the race, according to the poll.
A large racial gap is also present, with 93% of blacks supporting the Democratic candidate and none supporting Lonegan, according to the poll.
Five percent of likely voters say they remain undecided, while six percent say there is a "good chance" they will change their mind before next week.
"It's still not the predicted blow-out, but with a week to go, Newark Mayor Cory Booker hangs on to a nice, if not exactly comfortable, double-digit lead," Maurice Carroll, director of the Quinnipiac University Polling Institute, said in a statement.
Quinnipiac interviewed 899 likely voters in New Jersey by telephone from October 5-7, with a sampling error of plus or minus 3.3 percentage points.
