NJ Poll: Christie leads Corzine by 15

The Politico has this:

New Jersey gubernatorial candidate Chris Christie has opened his lead over incumbent Gov. Jon Corzine to a whopping 15 points, according to a new poll released today.

The new survey from Republican polling firm Strategic Vision gives Christie a 53 percent to 38 percent lead over Corzine, whose approval ratings have plummeted as economic tides battered New Jersey.

Only 4 percent of respondents told the pollsters they were undecided – that means this race is shaking out a lot faster than anyone in New Jersey thought, and that Corzine needs a game-changer to win back independents who have flocked to the Republican.

The poll, conducted July 17-19, surveyed 800 likely voters and has a margin of error of 3 percentage points.
