A new poll finds Republican challenger Chris Christie ahead of Democratic incumbent Jon Corzine in New Jersey’s race for governor. The Fairleigh Dickinson-PublicMind Poll of registered voters released Wednesday finds 45 percent favoring Christie, with 39 percent for Corzine. Fifteen percent are undecided. A previous FDU poll taken in April, two months before the Republican primary, had Christie leading Corzine 42 to 33 percent, with 25 percent undecided. Only one in five voters say they believe New Jersey is on the right track, and 54 percent say their view of Corzine is unfavorable. The telephone poll of 803 registered voters was taken June 22 through June 29 and has a sampling error margin of plus or minus 3.5 percentage points. AP
