The numbers must be worrisome to Corzine, considering he has spent some $23 million so far, most of it his own, while Christie has raised just about $11 million.
Independent Chris Daggett has a made a strong showing, and some believe he could be a spoiler. However, in the same poll, his numbers dropped from 11 percent to 7 percent in just one week.
Campaigns are going negative
Negative ads have become issues themselves, including one that takes a veiled shot at Christie's girth.
Gov. Jon Corzine says it might have been a "good idea" to use different wording in the commercial.
The ad accused Chris Christie of "throwing his weight around" to get out of traffic citations while he was New Jersey's top federal prosecutor. It included unflattering images of Christie struggling to exit an SUV.
Appearing Monday on CNN's "The Situation Room," Corzine said the choice of words may have distracted viewers from the real issue: abuse of power.
Christie has acknowledged that he's struggled with his weight throughout his adult life. He has called the Corzine ad "unseemly."
Christie to hit the road
Christie's campaign announced Tuesday the candidate will ride a bus to all 21 New Jersey counties between Wednesday and Election Day Nov. 3.
He'll be joined at various stops by former governors Tom Kean and Christie Whitman, and former New York Mayor Rudy Giuliani. The campaign initially said that Minnesota Gov. Tim Pawlenty also would come, but later said he would not.
The only break in the schedule is Saturday evening so Christie can join his family for some Halloween trick-or-treating.
