Among likely voters, Corzine leads Christie 37%-35%, with 6% for Daggett. 

"If Corzine gets his liberal/urban/Democratic base together he's going to open up a significant lead, forcing Christie to work the right," Shaftan wrote in his analysis.

The poll was conducted between August 12-21 with a sample size of 319 and a margin of error of +/- 5.49%.  The party breakout among respondents was 43% Democrat, 34% Republican, 23% unaffiliated.
